    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.

My best attempt

u/cantelope

"best" with what criteria?
u/ximavus

Here a TIP: you can change the Math.sin() with S(), Math.cos() with C() and Math.tan() with T()
u/joeytwiddle

It's good but it's tiny!
