    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.

A speaking dweet (international version)

u/joeytwiddle

Chrome users, if your utterance goes over 15 seconds, you may need to close the tab. http://tinyurl.com/chrome-bug-679437
u/cantelope

very clever :)... btw, which dweet of mine crashed your lappy? ...just curious
u/joeytwiddle

This is the one, it can reliably overheat my CPU: https://www.dwitter.net/d/2355 I think it's due to the size of the large squares. I have had to adjust the cooling thresholds!
u/cantelope

:/ sorry about that.
u/joeytwiddle

No worries Cantelope. Wow Mac has a lot of voices. The "Cello" voice is pretty funny! https://codesandbox.io/s/vq48b #audio #speech

A glowy curve, inspired by the inverted colors of https://www.dwitter.net/d/3015 by Cantelope

u/kchplr

Noticed it is very slow in firefox, has lot of artefact on Safari and doesn't even render properly in stable Chrome. The only browser rendering it correctly is Chrome Canary. Oh, well.
u/kchplr

Here is a version which renders correctly on stable Chrome : for(x.fillStyle='rgba(0,0,0,.1)',x.fillRect(0,i=0,2e3,2e3);i<7;Y=S(i*2+t),X=(C(2*i)+C(t+i+Y)),x.clearRect(960+X*450,536+Y*500,20,9))i+=.002
