A bit on the small side (on screen that is), but ok otherwise. Runs fine but a bit slow on safari, must faster on a recent webkit build.
Nice one.
Slow on Safari (Windows) indeed, will try Chrome and Firefox once I get home from work.

Slow but thumbs up for the effort.
Slow but pretty hardcore.
Amazing

Code:
Now 16bytes smaller and working in Firefox, Webkit & Opera.<body onload='t=C.getContext("2d");z=Math.cos;setInterval("u=z(a+=88);v=z(a+11);for(x=64;x--;)for(y=64;y--;t.fillRect(x*2,2*y,2,2))o=z(x/20)*16*u,p=z(y/20)*16*u,t.fillStyle=\"rgb(\"+(((o*u+p*v)|(o*v-p*u))&255)+\",0,0)\"",a=9)'><canvas id=C>Nice for a firstie
