    u(t) is called 60 times per second.
    t: Elapsed time in seconds.
    S: Shorthand for Math.sin.
    C: Shorthand for Math.cos.
    T: Shorthand for Math.tan.
    R: Function that generates rgba-strings, usage ex.: R(255, 255, 255, 0.5)
    c: A 1920x1080 canvas.
    x: A 2D context for that canvas.

This is nice, but not really in line with the concept of a dweet ;)
u/lionleaf

Nice! Is this the first interactive dweet?
u/PhiLho

A bit of cheating, but fair enough, as long as you are not imitated by lot of people... :-D
u/iverjo

This seems to be broken atm. Does not respond to mouse movements.

thank you for cleaning up my idea ;) your solution is very neat
u/iverjo

Thanks :) It lacks the yellow color, though. I'm not sure I could hack that in without removing the rectangles

Golfed a bit (128 characters): i=W=c.width=960;x.lineWidth=80;x.arc(X=250*t%W,200,40,G=.3-.3*S(X/29),6.29-G);x.stroke();for(;i>X;i-=190)x.fillRect(i,190,20,20)

u/sigveseb

Nice, is the compression worth the bootstrap overhead?
u/iverjo

Crazy stuff. How does it work?
u/3bl3gamer

No, it does not. Decompressor doubles characters number, but takes 75 characters by itsef. So no profit, just making some unreadable code even more unreadable :-)
u/3bl3gamer

It works by converting N utf-16 characters to N*2 bytes and then converting this N*2 bytes to N*2 utf-8 characters. This N*2 characters is JS code.
u/iverjo

A for effort
