    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.

For those who are wondering h is meant to just represent half the height of the screen. I just wound up using it in inappropriate places because it was roughly the right number for what I needed

Bah, and there I was thinking I'd got there first. I get crazy lag when trying to look back due to the infinite loading, so I've been unable to see what people have done already

Basic Unicode Chinese Character block 4E00–9FFF, (this is not all Chinese characters!). Progress bar on the left.

Wow! I mean, I know there are lots, but this just makes it seem incredible. To be fair I guess scrolling through and english dictionary would look pretty cool too (even though it's not quite the same)
u/Kalanchoe

oh, wow! I love it
