    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.

Very nice golfing. Let's see if we can fit a bigger pattern in a dweet.

Inspired by u/anotherkitten u/21medals This is more likely to draw something by focusing on the [x,y] = f(t) solution space and further reducing that to interesting ones by manipulating allowed input tokens.
u/tomxor

Familiar yet different every time :)
u/tomxor

Trust me, it will draw :P every time the comments bounce it's found a solution and assigned it, but not all combinations draw anything visible.

#Xorshift 32 #PRNG

u/tomxor

I felt that there are too many extremely unecessarily long examples of xorshift32 implementations out there, with lots of fluff around the outside. It's a very nice and simple little PRNG and this is all the code you need to turn it into a unit interval (i.e the type and range you get from Math.random()): (x>>>0) * 2**-32. This conversion method is far from perfect and results in some bias, but so does the PRNG itself...
