Water It or Not! at Ripley's Believe It or Not Museum in Orlando, FL.

 

Uses openFrameworks to track the magnets placed on the magnetic whiteboard wall. A front projector shows the digital water which can also be 'touched' by a person and the water will bounce off. Real world valves are used to control the amount of digital water coming from the PVC pipes. Each magnet displays unique animations when activated by water.
