 Nevermore
This Art Installation was submitted and created by William Saar
Nevermore is an interactive art installation based on Edgar Allan Poe's The Raven that uses a new physical interface in the form of a pair of wings. A person enters as the role of the raven by strapping on the wings and flapping his/her arms. The movement of the wings is captured by a BASIC Stamp® module connected to five  potentiometers mounted in the joints of the wings and is transmitted to a computer via the serial port. The computer animates a 3D-model of a bird inside a virtual world based on the motion capture data.
 You can visit my site at http://www.saar.se to see a poster and a detailed description of the project, Nevermore. The Interactive Flea Circus project that is also listed on my site also uses a BASIC Stamp microcontroller, but I don't have the schematics, nor any photos of the electronics. Five circuits exactly like the one in figure 5.29a of the BASIC Stamp Manual in the RCTIME section of the manual are connected to I/O-pins 0 - 4 of a BASIC Stamp 2sx chip. The resistance R represents a 50k potentiometer mounted in a joint of the wings and the capacitance C was chosen to be 2.2nF so that the BS2SX would be able to time all five potentiometers in one millisecond (not counting the pause that needs to be called before the RCTIME command is executed).
