    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.

#corruption #asymmetry

u/plusright

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

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
u/plusright

nice, thank you both.

possibly #symmetry

u/plusright

gotta find a more succinct way of writing for loops, this one just feels a little too dull
u/yonatan

c.width=999 for(w=i=40;i--;)for(j=16;j--;)s=i%2==0?-1:1,x.fillRect(-2*w+i*2*w+S(t)*w+C(t)*-s*w,-2*w+j*2*w+(C(t)*w*s),w,w)
u/yonatan

actually, the fillRect can go into the for loop's final expression, between the ; and the ) to save 2 more chars
u/plusright

aha! that's clever, thanks.
