    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.

WASD Snake!

u/Jenky

You can change the controls by editing 'dsaw' to any four letters, starting with whichever is to be "move right", going clockwise
u/donbright

the controls seem a bit unreliable on my sytem (firefox linux) but when it works, it is reaally cool, one of my favorite dweets ever. nice

font='9 em sans' also works :)

@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

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. :-)

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

Another fake gravity sim. This time, some particles get slingshotted out of the system, past escape velocity, others teeter on the brink, and others congregate at 0,0. After a while, the screen is full of a bunch of particles leaving, and others coming back in towards the origin.

your gravity sims are amazing.
u/z3vin

agreed
u/donbright

thanks this site is very inspiring
u/alien

WOW ,Hi what does this mean :D c.width^=0
u/donbright

alien it basically clears the screen to the default width. in detail, i think it is combining "binary xor" with "set equal to", so basically c.width = c.width xor 0, and since anything xored with 0 is itself, its basically setting c.width to itself.
