    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.

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

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

Pretty
u/cantelope

ppl seem to either love or hate my more visually stimulating dweets. I agree that it's pretty, but someone else complained that it is an epilepsy-causing abomination that should be stopped. :s

One of your dweets overheats my laptop and makes it shut down

Ripples! With proper quads instead. Add +Z*X-Z*16 after X*60 for perspective projection too (brings it up to 146)

u/FireFly

Another byte can be saved with with(x), but this causes a fair bit of slowdown for me. Thanks for some golfing tips from qfox and others on the jsgolf slack :)
