Tweenbots

Created by Kacie Kinzer as an interactive art project in New York, Tweenbots are "human-dependent robots that navigate the city with the help of pedestrians they encounter."

They roll around the streets with their little flag printed with a destination and a simple message asking passersby to help them get there. They are also, incidentally, the most precious little wonderful things ever invented. And I love them. (Thanks for the tip, Joy!)
