    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.

Can some one explain what the with(x) is doing ? please :)
u/lionleaf

Wow! That looks amazing. Love what looks like a white cube that vanishes in the beginning too.
u/nystrand

@alien: with(x) puts x in the scope so that you don't have to write the "x." part of x.fillRect, x.translate etc. So, it only saves bytes if you have more than 3 functions in x you want to call.

best fullscreen. Couldn't have done it without the help of the dark knight, who prefers to remain anonymous. :)

yeahhhhh!!!!! cool
u/cantelope

there's an odd bug in chrome where if hardware acceleration is disabled, or the dweet appears far down the page, the arcs close their paths and create unwelcome diagonal lines. I have a more robust version but it does not fit in 140b.
