    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.

Autostereogram Sphere 🌎

u/neimad

I see it! I've been waiting a long time for an autostereogram dweet.
u/Joachim

So cool!! Seems a bit flat for a sphere though :(
u/magna

Works really well!
u/magna

Joachim it could be that your eyes are overlapping slices that are too far away, maybe? Try full screen and getting closer to the screen.
u/magna

KilledByAPixel, do you think you can offset the pixels at a gradient instead of circle slices?
u/Joachim

u/magna Ooh I see it now! :D
