    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)

x.fillRect(960-t*50,q=t*99|0,q,4);x.clearRect(960-t*5,q,t*9,q**.5&1&&4) - there might be a better way without using clearRect

Precise paint. If you want to use it on fullscreen, change fs to 1

u/katkip

^ edit: isn't precise when fs=1
u/Fime

On mobile, at least in opera touch there is always an offset in dweets which use mousemove
