    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.

I wanted to make a tribute to https://twitter.com/BalintCsala/status/99216… but this is all I got so far
u/BalintCsala

Hah, thanks
u/joeytwiddle

I did write something which was technically more similar (points appear and disappear without moving) but it doesn't look any good at the moment

This one looks better in Chrome than in Firefox
u/joeytwiddle

Firefox users: please replace 50% with 33% or 66%
u/joeytwiddle

I guess this is exploiting rounding behaviour. RGB clouds emerge first, CMY later.
u/joeytwiddle

It has stopped working in Chrome. Now Chrome needs the same fix as Firefox!

Popped in to debug an ellipse for work. Felt rude not to leave a dweet.

u/jick

Oh, neat periodic clear trick.
u/joeytwiddle

I found that trick in a random dweet I saw recently. No idea which one.

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

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
