If 1K seems like overkill, then take a look at the releases by P01: http://www.p01.org/releases/ He's a maniac. His 252 byte voxel fly-y thing is nuts: http://www.p01.org/releases/minicraft/

That's incredible. I also love your use of "maniac" in this context.

JS1K was fun.

have a look at my entry: http://js1k.com/2013-spring/demo/1430

which is a stripped down version of this: http://jsexperiments.herokuapp.com/sph/

Cool site design. Nice easter egg, too.

I refreshed it at some point and I achieved "Refresh Prince of Bell Air". Nice sense of humour, and ridiculous page header (and I mean that in the most positive way). So impressive. :)

acko's website is one I have in my favorites bar. Love reading the stuff he puts there. Sadly I wish, as with many of my favorite development/science blogs he updated much more frequently.

as a complete aside - i have to say that i do love the visuals of the webpage itself :)

He has another post about making the webpage:

thanks, did see that too :)

Weirdly, I'm getting about double the framerate on the second, more complex demo (with volumetric light beams).

In the original there appear to be more iterations in the both of the loops. Something like 720 vs 250 iterations.

Also, in the original he is calling math functions a few more times in each loop.

Love the webpage!!

the fancy logo on that site gives me a "SecurityError: The operation is insecure." error in latest FF beta, resulting in a black background. apart from that the site works like a charm, but it's virtually unreadable.
