    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.

20 characters shorter

u/yonatan

10 more: for(c.width|=i=840;i--;x.fillRect(a*800+i%40*99-1e3,b*50,50,50))a=((b=0|i/40)%2?S:C)(t)

goodness gracious
u/New_Core

or even 13 shorter then that... ;) diffrent code tho.. for(c.width|=i=962;i--;)x.fillRect(i%37*99+800*S(t+i%2)-800,i%26*40,50,50)
u/New_Core

*noticed a small error.. (in72b) for(c.width|=a=i=840;i--;)x.fillRect(i%37*99+a*S(t+i%2)-a,i%22*50,50,50)
