I was curious if my cat would ride an electric skateboard, so I designed and built an electric skateboard for my cat MIDI to ride. Put a treat into the throttle lever, and she pulls it to get a snack and a boost!
I made a pinball game for MIDI the cat to see if she could learn how to use it. And the answer is MEOW! (That's cat for YASSSSS) Made mostly out of acrylic cut on with the Glowforge laser.
