    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.

Golfed even more :D

Some more golfing: w=c.width+=0;for(i=m=150;i--;x.fillRect(i/m*w,w/4+100*S(i/10+t/2),10,m*C(i+t)))k=C(t*2+i/50)*255,x.fillStyle=R(255-k/2,0,k)

Also, why are the edges cut off?
u/BuRRak

This is weird
u/hg

Edges are cut because the iframe doesn't take up the whole div.
u/BirdsTweetCodersDweet

Well that sucks...
u/BirdsTweetCodersDweet

hmm, stuff like 0.2px solid black seems to work for all edges though
u/BirdsTweetCodersDweet

0.4 gets cut off on the right, and at 0.5 our problems start -- weird... :/

A torus-like shape made of sin and cos spinning in 3D space. Credit to u/Xen for golfing.

Better with transparency, but 148 bytes -- t?0:s=0;for(c.width|=a=1e3;a--;x.beginPath(x.globalAlpha=.5))x.ellipse(960+200*C(a),540+200*S(a),90+30*S(a+s),90+30*C(a),0,0,7),x.stroke(),s+=1e-4

I dunno, see you all tommorow, I'm off to sleep :P
