    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.

#stereograph Cross your eyes until the images are on top of each other for a 3d effect!

u/taupelink

whoa
u/magna

Nice! I relax my eyes (i.e. as if looking at a distance) instead of crossing. Then the smallar squares appear closer, not farther away. But amazing regardless! More of this technique please!
