    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.

cool!
u/sfz

wtf is going on here?!
u/FireFly

The string embeds a tiny bitmap which is simply repeated :)
u/5Mixer

This is an awesome idea! I wonder what else you could do with using strings to encode more complex(?) data. Interesting.
u/PiggyClone205

When I read complex, I immediately thought of maybe importing other javascript and cheating a bit.
