    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.

Err, I meant for(i=u=~u*81&493;w=i--/4;)x.fillRect((t||S(i))*3e3-u*T%w,T=640+(i&5?i-u:u-i),t?w:u,t?2:i/u)

A nice round 2**7 chars. A bit of bitwise, ternary trimming and coefficient concessions
u/KilledByAPixel

nice! I'm surprised you didn't get rid of the Math.random()!
u/yonatan

nice golf, r=(t+i)**3.9%1 works too
u/tomxor

Yeah I was surprised to, I think this one is a bit more sensitive to bad distributions. Yonatan's is pretty good though.
u/pavel

X=t?X+r*50:0 -> X=t&&X+r*50
u/pavel

r=++t**3.9%1 saves 3 chars
u/pavel

Ah, no, it kills the sky/water.

i feel it is possible to somehow golf the random part by at least a byte but I still haven't found a way without major issues

shaved some extra bytes off and managed to get the ratio I was originally aiming for

u/donbright

really fun to play around with that o+=.1047 term.
u/donbright

and the i+= term as well. really cool

Based on this tweet: https://twitter.com/matthen2/status/14377160…
u/hvianna

Later I realized s*(r&m?-1:1) can be reduced to r&m?-s:s (duh!) which frees up enough bytes to use the original ratio I wanted (o+=.1047) - see the remix.
