    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.

16*16*8=2048~=1920 so using width
u/pavel

.43~=3**.5/4, 2.1~=2*Math.PI/3
u/pavel

120=0b1111000 so k&120=x*8
u/pavel

I'm using a single stroke and no moveTo. This is a single curve, just lined everything up.
u/pavel

d is horizontal offset, even rows are offset from odd rows. Using +4*t&1 to explicitly cycle the animation every second instead of implicitly cycling every 2 seconds. Longer cycle leads to z<0 and glitches or hexagons that don't reach the camera.

dweet stealer - choose and run another dweet

u/metamero

click on canvas to run selected dweet
u/BirdsTweetCodersDweet

Seems to me like you also need to scroll down and back up again (to pause the dweet and resume it) for it to run, after clicking on the canvas. Chrome {whatever the latest version is} on Elementary OS {also latest}.
u/BirdsTweetCodersDweet

Cool stuff though :P
u/metamero

@BirdsTweetCodersDweet thanks! yes, I couldn't figure a way to call playDemo() after dweet transition/reload (seems timers are also reset). so it'll need to get this "play" message from server when scrolling back. (made in chrome/windows and tested on firefox; same thing on scrolling, but mouse wheel event return different values on firefox)
u/katkip

Awesome
