Amazing, just amazing. Thanks alot. I would only suggest author to set og:image in your pages. When you share it on social media no image appears, you know how does it affect spreading, right? :)

#22Great work, we live in amazing times! I can't imagine how humanity will evolve from now on if knowledge is as available and as well and accessibly presented as it is these days!

#23What an incredible piece of work. I can only dream of having the patience, skill and drive to make something so beautiful and informative.

#24The site is the work of a guy, "him", and "his" work. We don't have to guess and say "them" and "their" work.
But it's way less effort than checking, isn't it?
The name in the footer isn't English, so it's hard to know from that and there's no about page that I could find. The Twitter profile makes it more obvious, but I only clicked on it to check because of your comment. Why bother??

#25It may not seem interesting at first, but I am intrigued by how they managed to draw the overlapping blades of the IRIS.

If you naively create 6 blades and rotate them around the pivot (the tiny screw), they will never overlap EACH OTHER. One will end up at the very top, and one at the very bottom.
If you know how this was created, please let me know.

#26I've seen a few of these kinds of interactive articles on hackernews but this is on a whole new level. Wow. One of the best explanations of just about anything I have ever seen.

Not sure I get your question, you want to know how it works in real life ? Have a look here: https://www.youtube.com/watch?v=cR7cibDvYyo

#28It's really fascinating - I had always assumed digital cameras had different sensors for different light colours like eyes do.

I think the question is how is this drawn on a canvas. It's not trivial, if I draw 6 shapes successively, one will be on top and another at the bottom, you would not see the tip of one at the top and the other part of the same blade at the bottom. Nicely spotted, interesting question!

Do you mean, how it was drawn using canvas?
I'm guessing they drew overlapped part of the last blade twice
