    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.

Thanks! It's the first time I've tried, so probably I missed a lot of tricks to reduce characters... Any feedback or tips are welcome! :D
u/13thptr

b is unused so you can remove it :)

Thanks a lot for the suggestions, @13thptr! Indeed, I forgot to remove the unused b and the characters you remove by avoiding the definition of p is also very nice :)

355/113 is a famous approximation of pi and here we need pi/5 which is perfect as 5 divides 355 giving 71/113
