    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.

Change .11 to another decimal number (e.g. .10 or .13) for a different pattern!

u/FireFly

Just that lil' bitmap in the centre (same way as in other dweets—each bit of each codepoint represents one binary pixel)
