I have been building a number of project models for my Capstone semester in architecture. I started with some simple prototypes using IR and photos sensors, linking into firefly on the second one. after that, I focused on sound level capture and manipulatable seating. the culmination project uses openFrameworks on the pc to feed data via the serial port to an arduino which runs some easy drivers controlling the steppers which power the movement in the model. Sorry there isn't much more info here, the videos I created of the projects cover most of the details.
Please check out the videos and let me know what you think
