    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.

Can some one explain what the with(x) is doing ? please :)
u/lionleaf

Wow! That looks amazing. Love what looks like a white cube that vanishes in the beginning too.
u/nystrand

@alien: with(x) puts x in the scope so that you don't have to write the "x." part of x.fillRect, x.translate etc. So, it only saves bytes if you have more than 3 functions in x you want to call.
