    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.

Wanted to see if I could use the box ascii characters for something. Drawing text takes up a lot of characters, but it turned out okay :D As a bonus, removing the '+1' on the final line makes the pattern squares!

Edit: Nope. Some golfing apparently means that isn't true anymore lol.

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)

How did you come up with this?

@badthai: First I made a classic tunnel effect (like this: https://www.dwitter.net/d/205). Then I made several remixes of it by tweaking parameters. This was one of the results. See also https://www.dwitter.net/d/106
