I started working on this idea probably 2 years ago and never re-opened the file until late October of last year.

The Chaos emerald backgrounds are honestly one of my favorite things about this idea.
This layout is kind of a mess but hopefully you get the idea of what the end result is going for:
A rotatable button or enamel pin that showcases many (but not all) Chao evolutions.

I never liked the fact that Sega marketed these little guys as having only 3 variants, when in reality there are potentially hundreds.
And that's a complaint I've had since 2003 lol.

I still cant wait for the day when I hold one of these in my hands. "Then I'll have made something" or so the brain tells me..
