As part of our final project at Imperial (first year), we had to complete a kernel for the Raspberry Pi, meaning building from scratch an emulator, an assembler, flashing an LED and doing an extension on our own.  After discussion and research made for our extension, we chose the idea of using the Pi as a controller to lighting systems. We did choose this idea knowing that it has the potential to amaze and grow with commercial significance (one of the main factors that we believe it is that no one ever used a Raspberry PI as a DMX Show Controller).
