    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.

can in theory generate almost any dweet, but will practically never draw a single pixel

if this does actually manage to draw anything for someone (or at least not throw an error), please let me know

There are 128**140 == 1.0218702384817765e+295 possible Dweets :) If one dweet eval takes 1ns (being very kind) that will take 128**140 / 3.154e+16 == 3.24e+278 years to permute (that's thirty-two duononagintillion four hundred unnonagintillion)
u/tomxor

I suppose I more useful estimate would be the probability of an evaluateable string string... No idea how though.

Hi there :) I had to delete #1215 because it froze the browser (due to some excessively deep recursion or something). Here's the code, for reference: (F=Z=>{for(x.fillStyle=R(W=2/Z*1e3,W/2,W/1),i=Z*Z*2;n=i%Z,m=i/Z|0,i--;n%2^m%2&&x.fillRect((n-t%2-1)*W,(S(t)+m-1)*W,W,W));Z&&F(Z-5)})(36)//rm

Trying to play with the raw image data is hard

u/cshadows

wow!!
u/tomxor

It is hard - shame there isn't a simple buffer to write to
u/nburn42

I wanted to build cellular automata based off raw data, but there is so much overhead involved.
u/nburn42

I'll try anyway.
u/tomxor

What do you mean by raw data? using the frame buffer for state? there are quite a variety of CA implementations here but they are mostly tagged gameoflife regardless of specific rule. I made a larger than life one recently that is capable of >1 radi moore neighborhoods
u/nburn42

I see some of your CA, the are awesome, I'll play around with some of your methods too.
