    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.

Clever! Why didn't I think of that :D

Doesn't work on chrome mobile? 🤔
u/sigveseb

Works now 🤷‍♀️
u/joeytwiddle

Stopped working now. I think the site has changed the way it executes dweets.
u/joeytwiddle

At present it should be .slice(109,-1)

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

It's curious how a small bug in the spiral code seems to have produced some straight lines

Minor remix that shows off the patterns in the spiral, as pointed out by sfz on the original dweet.

Added some fake transparency. But perhaps spending some chars to double up the encoding might help the most...
u/joeytwiddle

Or perhaps convert the surface into a Fourier sequence, then we can have lots of points!
