    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.

Seems to be easier to find good results if j=i%461 is restricted to primes.

u/KilledByAPixel

nice!
u/pavel

Weirdly the numeric error from approximating pi/3 seems to matter a lot.
u/tomxor

Yeah, I think it's because it causes a deviation in the sequence at j=0. Although the output of 0|3*C(r) generally gives the expected low period of +1,+2,+1,-1,-2,-1 as j decrements, it ends on a 3, but only when using lower precision PI/3. full precision PI/3 pushes all of the 2s into 3s, which can be corrected by lowering the coefficient to 2.9, but this also makes j=0 output 2 which then seems to destroy the complexity.
u/pavel

I tried getting rid of the sin/cos by using hex coordinates but I was unable to make a complex picture. Usually just one of the six slices drew-in.

Very cool! To fix the y slope effects, just change "Y=i/96" to "Y=i/96|0".

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.

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