Ant (name idea from Minecraft infinite snapshot)

u/tomxor

For a moment I thought it was langtons ant, but no, it's entropy's ant.
u/ximavus

Well I searched its named Langton's ant but because I'm a minecraft player I named it after the Minecraft one

I want to say avant-garde and 1930s, but I don't know why
u/taupelink

Hints of "Metropolis" maybe? (1927 but close enough).

u/magicmarc

First line as "a=b=>128*(S(t*b)+1)" brings this to 140.
u/andy

Thanks, that's right. Didn't even realize i was over 140 :)
u/lionleaf

Are you seeing over 140 characters? On chrome it says 140/140 at least.
u/andy

weird, yesterday it said 143.
u/michelinux

It's probably because on Windows the new line takes 2 characters ('\n\r'). Use ';' instead of new line and you should have a more consistent behaviour.
u/andy

still weird, i don't have any windows machines.
u/SpecialAgent

the simplicity of that zoom blows my mind, great work!
