"Hi everyone! Welcome to our stream where our fish, Grayson Hopper, plays a Pokemon game. Unfortunately, we don't have a dedicated light for Grayson at night as he lives in a tiny dorm room and we would rather not sleep with the light on. :( But in the future we will be getting him a dedicated lamp and improving the quality of the stream to include recent inputs determined by the motion tracking. Things can move a little slow, so another option we're considering is making the system distributed where we have a site where you can provide a fish stream link and we'll include it in the controlling."

Some people hooked up a webcam to a fishbowl and based on which parts the first swim that maps to a Pokemon control. But this is something you really need to see to understand.

So far 4 million people have been mesmerized by a fish playing Pokemon and I can't really blame them, it's a fun idea.
