    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.

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

u/joeytwiddle

I remember on some devices, fonts over a certain size just don't show. A workaround is to use a scale transform, or reduce the canvas size.
