OH! is a sculpture/controller for the lights on the geodesic dome at the Telus World of Science in Vancouver, Canada. The controller has 240 embedded sensors which communicate with science world remotely. It is wireless and battery operated. I worked on this as part of my role at Tangible.
I did R&D and interaction design on this project. I prototyped the behaviour and evaluated several potential sensing and communication technologies. I designed the sensors and coordinated their manufacture. I also coordinated another (super talented) developer to build the server-side things and worked with him to get it talking to the dome.
Here is a demo video of the project, and several images of prototyping and development.
