There's two fish in a tank, one says to the other, "Do you know how to drive this?"

I heard that Finns' make good rally drivers

Does it have an ejector seat?

[doodab]

Or forget where it's going every 3 seconds.

[KentPhilip]

Presumably it will just drive round in circles?

A company called Studio Diip has created a motorized go-cart. For fish. Though "why" is the first question that comes to mind, at this point we're only able to give you the "how." When Little Dory starts to swim in a particular direction, her movement is captured by a top-mounted web cam, processed by a Beagleboard and used to steer the Arduino-controlled carriage under her bowl. As seen in the video after the fold, that lets her follow her muse outside the aquarium's confines. We're hoping this experiment makes it beyond the lab one day, as we're pretty damned curious to see where a fish wants to go. ("Away from the cat" or "towards the ocean" seem like safe bets.)
