Nothing better than Cos by deobfuscate

function u(t) {

c.width=1920 // clear the canvas
for(i=0;i<9;i++)
x.fillRect(400+i*100+S(t)*300,400,50,200) // draw 50x200 rects

    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/vain

87 chars - you can use just C() for COS() instead the long way math.cos ~~~~ c.width+=0 for(i=0;i<18;i++) x.fillRect(C(((t*150)*(i+1))/1000)*960+910,a=i*50,100,100)

Vain, may be username is "deobfuscate" for a reason.

oh, ups... i'm sorry... did not saw/noticed it before. thx for the info ;-)

Ok, I completely forgot about dwitter's built in Cos, Sin, and Tan functions. I kinda ported this from a list of effects I have.

And, I kind of like to be able to read my code
