    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.

Same road but straight. - 63 characters golf

u/katkip

or even 76 bytes: x.fillRect(960-t*50,t*100,t*100,4),t%2<1?x.clearRect(960-t*5,t*100,t*10,4):0
u/yonatan

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
