    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.

Spinning 3D model. This one is pretty CPU-heavy, gotta compromise for size

u/sigveseb

Very nice!
u/p01

It looks super clean!
u/sigveseb

is it spinning clockwise or counter-clockwise? :)
u/FireFly

shhh… it's rotating CCW I think, but cheating with the Z-axis/depth ordering means the faces are kind of haphazardly drawn :P
u/Xen

its transdimensional, you meant to do it! ;-)

This is the strangest piano i've ever played, but good job!
u/Woodmouth

Also, i found a way to stop it, just press shift. (or any other key with a value too high or low to hear (At least i think that's what happens))

Check the old comments for some simple tunes to play. You'll need to click on the blank canvas for keyboard focus. Hit Space, Shift or Escape for "silence".
