Rolf van Gelder teaching Processing @ Hackathon - Internet of Things

The 24-hour Hackathon: Internet of Things took place from the 8th to the 9th of April 2011 at the MADlab. More than 30 participants participated in the workshops and in the development teams. 10 Die-Hards actually went through the whole 24-hours, and stayed in contact with other locations on Earth where similar events were being organised.
The workshops Processing, Techno Jewels, Arduino and Kinect hacking were inspiration for working on experimental applications with electronics, sensor data and the web.
