In this installation, a speed bag is mounted next to a digital picture frame on a wall. When a person punches the speed bag, photographs of Tulsa are flipped through on the digital frame. Depending on how hard the bag is hit, it varies the number of pictures the frame goes through. The photographs are snapshots of recognizable Tulsa locations I took a few years back.
I built custom hardware and software for this installation. The speed bag has a two-axis accelerometer, micro controller, and RF transmitter mounted inside it. There are no wires running out of the speed bag. A computer receives the data and a visual basic program I wrote displays the photographs.
