Well, you might disassemble a Radio Controlled (RC) car and rebuild it to be a remotely controllable cat laser harness:
Cat Car uses a steering wheel controller with an attached Arduino and gyroscope / accelerometer, which communicate with a cat harness via an XBee. The movements control a servo on the back of the cat, which moves around a laser pointer, propelling the cat forward, thus allowing the user to remotely control the cat.They have video at the link. I guess that I only have two things to say about this:
1. This is why were were able to beat the godless Ruskie Commie bastards.
2. Lissa, you're welcome.
But this brings to mind what is perhaps the greatest Superbowl commercial ever:
Git along thar, little kitty.
