    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.

u/iverjo

Kinda reminds me of Solitaire on Windows 3.1, where the cards would bounce around (in slow motion, due to insufficient hardware) after I won a game

Two dancing torus. "var" is not needed, but performance (fps) is better with them.

u/username

But if you do not specify anything, it will be a var anyway?
u/yonatan

It'll be global, which means it can be accessed outside of the u() function, which kills some compiler optimizations
