    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.

Expression Miner (bruteforce)

u/joeytwiddle

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

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

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

first fullscreen detector? if you fullscreen this dweet, you will see the word "fullscreen". this concept is based on css #trick

u/katkip

I initially used x.fillRect(960,540,90,90) as test that's why i haven't deleted it

d/14992 detects if fullscreen or not...

Going for a weave texture

u/KilledByAPixel

nice!
u/clauswilke

Was mostly just trying to understand your code. The C(i*i*t) is just to generate randomness, correct? And instead of transparency, you draw fractional pixels.
u/KilledByAPixel

that's pretty much it. C(i*t) gives a good random walk that varies slightly around 0, one of the smallest ways to make noise like this

i'm sure somebody else can be more clever about this. still not shorter than the string "an undefined infinity object" but that's not really the point

You can do [C(),''+u.z,1/0,typeof{}].join` ` to save two chars
