    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.

Sombrero function. Added +j (in fillRect x coordinate) to add perspective. Changed -64/+64 ("for i" and "for j") to other intervals so it can fit the image better and also removed .7* multiplications to get more space for equation.
