    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.

oh you sly dog very well done
u/pavel

u/jylikangas

Very cool! You can save 3 bytes by removing the unnecessary %1 from t when calculating a and also doing <<7 instead of *128. If someone is wondering how this works using a+1 instead of a at the end may help. :)

Removing %1 at the end breaks the animation on my iPhone.
