    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.

Stopped working now. I think the site has changed the way it executes dweets.

At present it should be .slice(109,-1)

Unfortunately I couldn't use alert(S) so I had to drop some numbers!

Tryn=4 and either D=[1,3,7] or D=[1,1,4,27] #unimproved

Rather than searching, it might be more productive to display/draw some of the unusual small expressions, so we can look for ways to use them in future

E.g. for D=[7,2,5] and L=5 it produced 5/i^7

Nice #fuzzing

😂 the code is a mess but its useful. The ascii vomit encodes the valid next char to speed things up.
