If you know how to interface directly off the expansion slots, you can
control banks of lights by calling specific memory addresses. You can call
256 (8-bits) position motors for yokes and moving light systems, or make
256-step dimmers, or imagine 256 coloured gels! The possibilities are
endless in the digital realm.
