    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.

Trying to eval a random string, pauses when its compilable

u/21medals

Most of them are just one big comment or one long string though
u/katkip

nice!

99% copied from tomxor's dweet though!

eWuW='.,gttb/PIdd ]I]8fte6?Abnu80<~pI~u' It's still quite impressive that it can find any... I guess reducing the length to 40 substantially increased the probability. The next logical progression would seem to be to let it accumulate shorter evaluable strings and compose a larger one from them.
u/tomxor

If you can also fit in the requirement to reduce entropy then you have the seeds of life inside a dweet :D
u/katkip

yeah
u/katkip

it can be faster with another for
u/tomxor

I tried that but couldn't fit it, so I did the opposite - reduce the search space - I made one that constructs expressions for f(t) and does the canvas bit for it so it actually draws: d/12492
