External: The tweenbots project by kacie kinzer

What is a Tweenbot? From the page:

Tweenbots are human-dependent robots that navigate the city with the help of pedestrians they encounter. Rolling at a constant speed, in a straight line, Tweenbots have a destination displayed on a flag, and rely on people they meet to read this flag and to aim them in the right direction to reach their goal.

What I find most interesting is that not a one Tweenbot was lost, they always made it to their destination. Awesome.
