Look at de cute robotron made of cardboard! The idea behind Tweenbots is to explore is to see if a human-like object could traverse the streets of New York.
Basically the Tweenbots have a destination on their flag, and are left alone to see if people will help them get to their destination. Neat! It would be cool if there were instructions on the site as to how to build your own, and then they could travel all over the world!
