    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.

u/alien

wait what is going on here D: , could explain this x[i=frame] and T=x[i] plz
u/alien

How can you add T a numer, isn't T a defined function?
u/iverjo

frame is a number that starts at 0 and increases by 1 for each frame (this is actually a somewhat "hidden" feature in dwitter, and can be used as an alternative to t). T is initially a defined function (by dwitter), but the code in this dweet sets T to something else before a number is added to it. x[i=frame]=300 has the same result as i=frame,x[i]=300 because i=frame returns the new value of i
