Surprised this made the news today: it was built in 2004! :D Still great though.
Really? How? It looks like it's based on HTML5 Canvas, and that came in like 2010? Or am I wrong?
The original was done in Flash. Someone must have transitioned it over to HTML5. The original was also interactive. By clicking and dragging, the viewer was able to control the speed. I remember it was also made into a screensaver.
I love this kinda stuff and always wanted to build one, but never have.
Just one of those things, I suppose :D
