    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.

29byte quick play, could be lower

u/CaptainMeat

how does any of this work
u/pavel

throw[a,b]=t?[b,a+b]:[1,1] is shorter and easier to read but throws both numbers :/

nice! 26bytes!
