Teaching fish how to drive, however... now that's the stuff on which this miracle we call The Internet is built.
The concept is simple to understand, though the actual product seems pretty sophisticated. A camera watches the fish swimming in its tank; the image recognition software determines the direction the fish is headed, and then steers the toy-car underpinnings in that direction. Just add batteries, and you've got one super-mobile house pet. Just keep him away from the bathroom.
