What’s a squirgle? Is it contagious? Is it, as the internet defines it, the sound a cat makes between a purr and a meow? It’s neither! A squirgle is an optical illusion object that looks like both a square and a circle depending on the angle.
We 3-D printed a squirgle this weekend, and held it up to a mirror and: voila! Squirgle!
See for yourself!
