Some smart people over at DIIP have put together a little aquarium on wheels so that a goldfish can successfully navigate this strange land world without issue. We hear the Little Mermaid is pretty damn jealous.
Using computer vision to detect the position and swimming direction of the fish, the contraption is steered based on the direction the fish wants to swim in. It is awesome. Although having watched the video, I might have stuck a lid on the aquarium.
