More colors (noisier)

Room for perf improvements, including those scanlines. But it works!

hum, it seems to hit a color-cycling state way before it get interesting... shouldn't there be squares and spirals ? or maybe I'm thinking of another type of cyclic cellular automaton ?

@ultrabrite the cycles become more apparent as you add more colors! I just upped it from 8 -> 12, and it looks a lot less noisy.

Do you know if there's a way to update the version hosted here?

when submitting, choose "Update a cartridge thread", and choose this one... you'll get a new tag, either add it at the top of your post or simply replace the old one.

I'm not sure it's only the number of colors though.

here's one I made weeks ago. its behaviour is quite different, and more akin to what's on wiki cca
but maybe we're not on the same rules, I'll have a look at your code...

sorry for the weird style, I think I started this as a tweetjam contrib :)
copy,paste & run

s=127m=128p=16r=rnd g=pget
--for i=0,s*s do pset(r(s),r(s),r(p))end
for j=0,s do for i=0,s do pset(i,j,r(p)) end end
for j=0,s do 
for i=0,s do
local c,k,l,r,u,d=g(i,j),(g(i,j)+1)%p,(i+s)%m,(i+1)%m,(j+s)%m,(j+1)%m
--          g(l,u)==k or
            g(i,u)==k or
--          g(r,u)==k or
            g(r,j)==k or
--          g(r,d)==k or
            g(i,d)==k or
--          g(l,d)==k or
            g(l,j)==k or
)then   c=k end
memcpy(24576,0,8192)flip()goto z

edit: yep, we're on the same boat. and you're right, the number of colors is a real game changer!

Thanks! Updated.

Unless I'm misunderstanding, that is top speed for changing pixels to new colors ?
