    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.

I thought the characters were underdeveloped but the effects hit the spot!
u/joeytwiddle

I was really confused why some of the lines appear softer than others. Finally realised it's because the canvas is scaled down

nice use of emoji as coloring
u/recursive

That's a very convincing woven rug.

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

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. :-)
