We made an interactive cat laser game that’s controlled via mobile, and also has an automatic mode. We used a pan-tilt unit we found online (info and credit later on in this post), adjusted it to fit the laser diode, connected it to our phone with a Bluetooth module and started playing around with Pepper the cat, who turned out to be quite the Flamenco dancer.

Cats didn't invent the can opener. They domesticated it instead.
