    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.

This is nice, but not really in line with the concept of a dweet ;)
u/lionleaf

Nice! Is this the first interactive dweet?
u/PhiLho

A bit of cheating, but fair enough, as long as you are not imitated by lot of people... :-D
u/iverjo

This seems to be broken atm. Does not respond to mouse movements.

When using https://beta.dwitter.net you can toggle the compression. So copy-pasting the code in the comment isn't necessary.
