    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.

119 (okay I should do something else now): "3E71EAA0325D3E7C".match(/../g).map((s,v)=>{for(i=128,h=0;i>=1;i/=2,h++)parseInt(s,16)&i&&x.fillRect(h*99,v*99,99,99)})
