    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.

I could save 4 bytes by using t*60 instead of frame and removing the 0 in decimal numbers but whatever

Best brainfuck interpreter I could do in 140 characters, super bad code. You need to change the Q variable to your code for it to run. There are no loops or an input, but the output works just fine.

u/BuRRak

The Q variable declaration is there just so you know what to edit, it could be left out as it is not used anywhere in the code again
u/BuRRak

The output also throws a 0 before every other output
