Visitors are challenged to place the correct dinosaurs into three diaramas representing different time periods. RFID tags are embedded into the dinosaurs allowing wireless movement between areas.

2003 :: St. Louis Science Center Mountain Building Exhibits

Designed and built controls for two mechanical exhibits that depict how mountains are formed. Used optical encoders and programmable controllers to control a flow of lights behind a Duratrans graphic synchronized with the mechanics to simulate molten rock moving under the Earth's crust.

2003 :: St. Louis Science Center Volcano Exhibits

Designed and built controls for two volcano exhibits using programmable micro-controllers. Visitor controls rising flow of lights behind a Duratrans graphic to simulate magma with a joystick. At the "point of no return", the joystick rumbles and a video plays showing an actual eruption.
