    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.

Broken parallax scrolling effect (only works if you wiggle your mouse over the dweet while you scroll the page)

u/joeytwiddle

I tried various things but I couldn't find any way for the iframe to know when it has been scrolled. :-/
u/katkip

It impossible. Iframe's cursor doesn't update if mouse isn't moving inside iframe

Riff off of Katkip's great dweet two days ago. This is what happens if you floor the rotation angle.

Nice! If you edit another dweet you can hit Remix to post it.
