also: bitwise operators are really, *really* fast

things i have learned:
1. calling SDL_UpdateRect per-pixel is so much better than SDL_Flip every frame
2. 0xFF is longer than 255
3. having a square window saves bytes just because you dont need seperate w,h variables
4. arrays suck use really long numbers containing all of your values and iterate them with bitwise operators

bits[x] = bits[max(0,x-1)]^bits[x+1] for x in bits
that's literally the basis of the entire demo

@aeonofdiscord if you can figure out how to add a donk to Rule 90 (cellular automata)

@aeonofdiscord that would be extremely hard to do especially considering the demo is currently 495 bytes out of 500
unless you mean like record the demo and add a donk to it

it actually continues forever but that's the first loop

here's a view of what the demo outputs
thoughts?

this was Really Heckin Hard to golf down to 500 characters but it's a really neat demo with both sound and picture stuff!!!

from ctypes import*
from struct import*
from subprocess import*
p=480
k=p*4
S=CDLL('libSDL.so')
u=S.SDL_SetVideoMode(p,p,32,0)
r=unpack('iPiihP',string_at(u,40))
f=S.SDL_UpdateRect
a=0
c=range(p)
e=1<<(p/2)
s=Popen(['aplay','-r2000','-N','-B0'],stdin=-1)
while True:
a+=1;
for i in c:
e=eval('0b'+''.join('01'[(e>>max(0,j-1)&1)^(e>>(j+1)&1)]for j in c))
for x in c:
h=(255,0)[e>>x&1]
memset(r[5]+(x*4+a*k)%(p*k),h,4)
s.stdin.write(chr(e>>x&255));
f(u,x,a,1,1);
if a&8:f(u,0,0,p,p)

i actually like this better than the sierpinski i was going for

Hmmmmmm https://computerfairi.es/media/KcMool50s75McDruxhc

hmmm this doesn't look quite right https://computerfairi.es/media/w8M1LyFNUHee6x5OxUw

rule 34 (cellular automaton)

@aeonofdiscord nope, it's probably doing the same thing as me though, because im just writing the audio data to pixel memory

@aeonofdiscord i meant like "this code is not very optimal at all"
also the end effect is not exactly what i wanted which is "screenflips and audio run at same time"

@Gargron prayers

@Elizafox dicot

remember that login prompt vnc wget thing i found? well i found another server it really tried to go at too!! i like how it stretches out some letters it makes it look really eager https://computerfairi.es/media/9H0s0Fsz_INAXZrVL6k
