is that the name the AI gave it, or you did when you copied the AI's code?
u/Bloodyaugust

Excuse me? I wrote this code, but you can take your hostility elsewhere.
u/rodrigo.siqueira

I like this #spiral and your code. A tip: you can remove "{" and "}" to save 2 characters. I also noticed that you have *64*1.5/32 that can be replaced by just "*3"
u/Bloodyaugust

Nice! I didn't re-crush this one after changing some of the variables as I was still under the char limit. Excellent point about the brackets, I'll keep that in mind for the future.
