Hi all! I’m Aleix Ramon, the music composer of the soundtrack.<p>Since some of you asked, here’s the soundtrack on Bandcamp: <a href="https://aleixramon.bandcamp.com/album/size-of-life-original-soundtrack" rel="nofollow">https://aleixramon.bandcamp.com/album/size-of-life-original-...</a><p>There you can download it in high quality, and it’s a pay-what-you-want: you can get it for free if you want, or pay what you feel like and support me. Either way, I’m happy that you enjoy it!<p>The music should also be on Spotify, Apple Music, and most music streaming services within the next 24h.<p>A bit about the process of scoring Size of Life:<p>I’ve worked with Neal before on a couple of his other games, including Absurd Trolley Problems, so we were used to working together (and with his producer—you’re awesome, Liz!). When Neal told me about Size of Life, we had an inspiring conversation about how the music could make the players feel.<p>The core idea was that it should enhance that feeling of wondrous discovery, but subtly, without taking the attention away from the beautiful illustrations.<p>I also thought it should reflect the organisms' increasing size—as some of you pointed out, the music grows with them. I think of it as a single instrument that builds upon itself, like the cells in an increasingly complex organism. So I composed 12 layers that loop indefinitely—as you progress, each layer is added, and as you go back, they’re subtracted. The effect is most clear if you get to the end and then return to the smaller organisms!<p>Since the game has an encyclopedia vibe to it, I proposed to go with a string instrument to give it a subtle “Enlightenment-era” and “cultural” feel. I was suspecting the cello could be a good instrument because of its range and expressivity.<p>Coincidentally, the next week I met the cellist Iratxe Ibaibarriaga at a game conference in Barcelona, where I’m based, and she immediately became the ideal person for it. She’s done a wonderful job bringing a ton of expressivity to the playing, and it’s been a delight to work with her.<p>I got very excited when Neal told me he was making an educational game—I come from a family of school teachers. I’ve been scoring games for over 10 years, but this is the first educational game I’ve scored.<p>In a way, now the circle feels complete!<p>(if anyone wants to reach out, feel free to do so! You can find me and all my stuff here: <a href="https://www.aleixramon.com/" rel="nofollow">https://www.aleixramon.com/</a> )

The dynamic soundscape is delightful, as it subtly adds instruments and musical texture as you progress. And going back down the scale regresses it to simple again. Smoothly done.<p>It reminded me of Operation Neptune (1991): each level starts with just one channel, probably percussion, and as you progress through the rooms it adds and removes more channels or sometimes switches to a different section of music. It is unfortunately all sharp cuts, no attempts at smoothing or timing instrument entry and exit. A couple of samples: <a href="https://www.youtube.com/watch?v=S0LNaatyoQk" rel="nofollow">https://www.youtube.com/watch?v=S0LNaatyoQk</a> is an hour of gameplay revelling in “the dynamic and sometimes beautiful music of Operation Neptune” using a Roland MT-32 MIDI synthesiser; and <a href="https://www.youtube.com/watch?v=wPxEdQ4wx9s&list=PL3FC048B134B3D9D8&index=8" rel="nofollow">https://www.youtube.com/watch?v=wPxEdQ4wx9s&list=PL3FC048B13...</a> is the PCM files used on some platforms (if you want to compare that track with the MT-32, it starts at 28 minutes).

Neal delivers. I recently learned that viruses are not considered living being, but I'm nevertheless happy they're included here because they're both relevant and interesting in this context.

If you’re interested to read something on that topic I highly recommend the essay "That's About the Size of It" by Isaac Asimov (in his book "View from a Height").<p>He argues that human perception of animal size is skewed because humans use themselves as a benchmark.<p>He takes a logarithmic approach to illustrate where humans actually fit within the overall scale of the animal kingdom. We are way larger than we think we are!

Nice display, but it starts off with misleading measurements of DNA. The spacing between DNA base pairs is 0.34 nm, so the 10 base pairs pictured are in fact 3.4 nm. But the DNA in a single human cell is about 2 meters, and chromosome lengths vary from 2 to 10 cm. I am skeptical of the hemoglobin vs ribosome sizes as well; hemoglobin has a molecular weight of about 60,000, while ribosomes weigh more than 5 million.

It seems to be like some of the scales slightly off?<p>If you are looking at the ladybird (ladybug) with the amoeba to the left, the amoeba isn't an order of the magnitude smaller - it would actually be visible by the human eye (bigger than a grain of sand)? Indeed, the amoeba seems the same size as the ladybird's foot?<p>Similarly, this makes the bumblebee appear smaller than a human finger (the in the adjacent picture), which isn't the case?

One of the books that got me introduced to this fascinating aspect of our natural world is John Tyler Bonner's Size and Cycle. It has features amazing log-log plots of how different organisms from grow with time: from eggs to full-grown organisms. This kind of visualisation gives you a different perspective on growth and scale<p>For example, Sequoia gigantea Sequoia is the largest tree and can be effectively compared to the annual plant shown above. Fertilization and the early growth to the seed stage are essentially similar, but because of the cambium and the possibility of secondary thickening, the size of the tree can increase enormously. As can be seen from Figure 1 in the text, the sequoia does not begin to set seed until it is sixty years old and eighty meters tall.<p><a href="https://postimg.cc/hfdGGJ8H" rel="nofollow">https://postimg.cc/hfdGGJ8H</a>

Maybe it's a stupid question, but how does the poliovirus "work"? Like at this scale, the DNA strand is still pretty visible and a decent-ish percentage of the polio virus in size.. is it just a ball with DNA inside and not much else? How does it pack enough DNA to replicate itself into it's own size at that scale?

I like it, but the switch from metric to inches is confusing, and I think introduces a bug - there's no way a sea snail is 5-6 neurons high.

If you liked the first half of this site and want an extension, Cell Biology by the Numbers (2015, Milo, Phillips, <a href="https://book.bionumbers.org/" rel="nofollow">https://book.bionumbers.org/</a>) is great and has a similar intuition-building fun sense about size as well as various other measurements, including weight, time and energy at the atomic to micro-organism level.

I would like to play an open world game (like Minecraft) where 1 in-game meter equals 1 micrometer in the real world. That way, one could get a feeling about the scale of things.

It makes me emotional when I think about where life started and what it evolved into. Life created so many different types of organisms, each having different features while maintaining the equilibrium of the planet. From bacteria, to massive dinosaurs, to tiny homosapiens who inevitably control the largest organisms.

This has DNA as the smallest object and has a large protein next to it, so it misses the fact that a gene's DNA is almost always larger by weight and volume than the protein it encodes.

Very cool. I was surprised that orangutans are described as being only 2 feet 9 inches tall, I think most are a bit larger. Maybe when sitting they're under 3 feet? From wikipedia:<p>"females typically stand 115 cm (45 in) tall and weigh around 37 kg (82 lb), while adult males stand 137 cm (54 in) tall and weigh 75 kg (165 lb). The tallest orangutan recorded was a 180 cm (71 in)."

Reminds me of the video game Everything. Its a really cool game where you explore the various scales of the universe.

If anyone wants to set this up to auto-run all the way to the right and then all the way back to the left, here is a vibe-coded (sorry) browser console script. Makes a great "screen-saver" if you kick off the script and then put your browser in full screen mode :)<p><pre><code> (function() { let direction = 'right'; // Start by going right let intervalId; function getCurrentAnimalName() { const animalDiv = document.querySelector('.animal-name'); return animalDiv ? animalDiv.textContent.trim() : ''; } function pressKey(keyCode) { const event = new KeyboardEvent('keydown', { key: keyCode === 37 ? 'ArrowLeft' : 'ArrowRight', keyCode: keyCode, code: keyCode === 37 ? 'ArrowLeft' : 'ArrowRight', which: keyCode, bubbles: true }); document.dispatchEvent(event); } function autoScroll() { const currentName = getCurrentAnimalName(); if (direction === 'right') { pressKey(39); // Right arrow if (currentName === 'Pando Clone') { console.log('Reached Pando Clone, switching to left'); direction = 'left'; } } else { pressKey(37); // Left arrow if (currentName === 'DNA') { console.log('Reached DNA, switching to right'); direction = 'right'; } } } // Start the interval intervalId = setInterval(autoScroll, 3000); // Log start message and provide stop function console.log('Auto-scroll started! To stop, call: stopAutoScroll()'); // Expose stop function globally window.stopAutoScroll = function() { clearInterval(intervalId); console.log('Auto-scroll stopped'); }; })();</code></pre>

It claims a banana isn't technically living, but a banana has living cells so I'm not sure how accurate that is. I'm not sure when they're all considered 'dead' after harvesting though - maybe some wiggle room there.

Nit: the tool-tips on the action icons in the top-right aren't consistent.<p>When music is playing the tool tip is "unmute" which is a verb. It should either be "mute" (to indicate what clicking will do) or "unmuted" (adjective) indicating the current state. Similarly, when the music is muted the tool-tip should either be "muted" or "unmute".<p>I'm not sure _which_ is wanted (verb or adjective) because the ruler tool-tip uses "Hide Ruler" and "Show Ruler" (verb), while the units tool-tip uses "Units: imperial" and "Units: Metric" (adjective). The info tool-tip ("Info") is also an adjective.<p>For consistency, I'd use a verb-phrase in all the tool tips:<p>- "Show info"<p>- "Switch units to metric/imperial"<p>- "Hide/show ruler"<p>- "Mute/unmute music"<p>I mean, I know this is pedantic nit-picking, but the site is so perfect, what else am I going to do?

When you reach the end of the test it asks for email, and then ultimately wants $1 to get your results. If you pay by credit card due note that there is an auto-checked box for some $29.99 per month subscription for... something.

double clicking makes the animation jitter. ive had to deal with matching derivatives of smooth slopes in rendering as well. the animation seems to be finite time (and so variable velocity) and mashing click is just updating the final point without matching the current derivative.

A week ago, I learned that animals weren't bigger in the past.<p>Sure, there were dinosaurs that were quite big, but they weren't living all at the same time. So there was maybe a big one, that died out, and the next big one would evolve much later.<p>As this project shows, the biggest animals and plants are living right now.<p>Also, we're living in the time with the biggest spiders in history. Somehow they don't get that big on average. Turns out, the high oxygen levels in the past didn't affect arachnid sizes as much as insect sizes.

The Japanese spider crab being the same size as a tiger shocked me.

Are there supposed to be pictures? I passed a human silhouette, but that was it.

Cool, but a little more thought on the content rather than the presentation would improve it. For example starting with an arbitrary segment of DNA double helix and saying how "tall" this arbitrary segment is, is just silly.<p>Instead, it should show how _wide_ it is. And for extra coolness, keep it in frame, coiling longer and longer as you go, and eventually have the same strand, which has been with us all the time, as a specific example (e.g. human chromosome 7 or some such) by _length_

Visually this is nice, but navigation-wise I absolutely hate the UI.<p>I don't want to have to keep on scrolling to "discover" new images.

The visual scale seems off, especially on the smaller end of things. Also, are Velociraptors really that small? Jurassic Park lied to me.

I wish Neal would do behind the scenes, how he built this art. I wonder whether LLM assistants like Claude Code make such an interactive show more feasible.<p>He previously did a game "Infinite Craft" which leveraged Llama models. However, I was only able to find an outdated blog from 2019.

Sorry to say that my first reaction was that this is heresy. . . all this talk of <i>science</i> is a hoax.<p>But then the music calmed me right down and I wended my way through, not understanding 99% of what I saw but in awe of nature and Neal's art nonetheless.

Interesting things from this:<p>- Smallest animal: Myxobolus Shekel. Smaller than a WBC at 10 micrometeres.<p>- Biggest butterfly: Queen Alexandra's Birdwing. Bigger than human brain at 18cm.<p>- Largest insect to ever live: Meganeura (283 MYA). At 40cm long, a dragonfly larger than a house cat.<p>- Rafflesias are larger than German Shepherds<p>- Earth's largest crab: Japanese Spider Crab. 1m, legs pan of 3.75m. More than half the size of a human.<p>- Always thought Mososaurs were largest animal to ever live but it's the Blue whale at 26m. I don't think I ever appreciated how unfathomably huge they are. (The largest Mosasaur found was 13m. There's a speculated size of 17m as well.)<p>- World's largest living tree: Hyperion - a giant redwood in california at 115m.<p>Love seeing something so polished and inspiring. Amazing illustrations and even better music.<p>Thanks Neal for these projects!
