As part of the exhibition "Zien is Geloven" at the Mozes and Aaronchurch, I created the software for an installation by Esther Verhamme.
The installation is a mixture between a confessional and a slot machine. Visitors are asked to kneel down on the padded bench and put 20 eurocents in the machine. Having done so, the machine comes alive, quickly alternating frames from different movies on the screen, like a slot machine. Having slowed down, it shows one randomly picked movie clip in its entirely.
I reverse-engineered an existing hardware solution consisting of a matrix panel wired to a coin acceptor, and wrote new code using Sparked to control the user interaction and display the video clips.
