TetraBIN used MF- C18 pixel, lights up when you drop rubbish in it, and in a mimic of an old-school computer game, tracks the rubbish in shape and size. It gets interesting because there’s a game component: you have to rubbish into the bin at the right moment to advance the game. It’s designed by Steven Bai and Sam Johnson from Sydney Univercity. Bai and Johnson developed this project for a class taught by Dr Martin Tomitsch, who specialises in the study of how tangible computer interaction can be applied to everyday life. http://www.vividsydney.com/events/tetrabin
