    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.

It began as a quick experiment to generate the Cardioid, bacause of today. Swap 't' for 2 to see it. Happy valentine's day!

u/Feiro

To clarify: Cardioid comes from 'heart' in Greek.
