    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.

Tapestry #1

u/z3vin

nice use of emoji as coloring
u/recursive

That's a very convincing woven rug.
u/sigveseb

very nice! also looks quite different from platform to platform (windows, mac, android, etc)
u/magna

Looks super great on Chrome on macOS.

font='9 em sans' also works :)
u/nonce

@donbright great tip!
u/cantelope

'9em x'' seems to do the same thing as '9em sans' ¯\_(ツ)_/¯
u/donbright

this reminds me of an old carnival ride in my home town, it was called Phantasmagoria, no longer in operation, but you would ride thru tunnels of glowing pillar-gates. good times. nice job

u/recursive

Reminds me of clockwork orange.

Love it! did a quick remix with the Russian П in sans-serif just to see what a tunnel might look like: https://www.dwitter.net/d/2332 and got a weird thing happening on the floor. :-)
u/mxfh

Trigrams ☱ and 🀹 Domino tiles work great too. Still if anyone could offer a 1D Noise/Pattern method for pure slit-scan goodness? https://vimeo.com/41747091

Wow, you get some cool patterns if you change the .02 to .1 thru .9

There are so many fun things to try. Try changing the ❤ to different letter or symbol. Also if you make the G,B out of sync it goes funky.

Try strokeStyle=hsl(${t*500},99%,50%) also
u/cantelope
