New #asymmetry dweets

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.

adding color is difficult! I want to do more with it but can't beat the character count.

few more bytes for you... c.width|=r=200;for(j=20;j--;x.fillStyle=R(0,0,0,.8))for(i=20;i--;)x.fillRect(r+r*S(i+t)*j/2,T(t/j)*r+r*C(i+t)*j/2,z=r-i*j,z)
u/pavel

x.fillStyle=R(0,0,0,.8) -> x.globalAlpha=.8

nice, thank you both.

You've reached the end.
