    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.

Notice how the objects 'in front' are always drawn 'in front'
u/pavel

This requires a bunch more chars and is only needed when objects have unique colors, which requires more. It seems impossible to do this without compression.
u/pavel

Pretty simple technique, when generating the 3d points instead of directly drawing them, store them in an array, sort it by depth back to front, then draw.
u/keithclark

175. Removed need for reverse() by reversing the projection (far points are painted near and vice-versa): for(c.width|=o=[i=w=960];i--;)o[i]=[C(a=i-t/9)*C(b=i*20),S(a)*C(b),S(b),hsl(${i},69%,50%];for([Z,X,Y,x.fillStyle]of o.sort())x.fillRect(w+w*X/(j=2.1-Z),540+w*Y/j,s=50/j/j,s)

158 - for(c.width|=o=[i=w=708];i--;o[i]=[C(a=i+t)*C(b=i*20),S(a)*C(b),S(b),R(a)]);for([Z,X,Y,x.fillStyle]of o.sort())Z-=2,x.fillRect(960+w*X/Z,540+w*Y/Z,s=50/Z/Z,s)

That would be a tetrahedron. Pyramids usually have a square base.

The music slowly changes over time and will not stop on its own. This is a new idea combining the oscillator setup with byte beat music to allow for enough space to write graphics code!
