This is the Flaming Lotus Girls fork of Open Pixel Control, which has been modified for use with our art piece, Soma, currently on permanent installation along the San Francisco waterfront. If you're interested in OPC in general and not specifically for use with Soma, you probably want the usptram version, at https://github.com/zestyping/openpixelcontrol. For more information about using OPC to develop patterns for Soma, please see https://github.com/FlamingLotusGirls/soma/tree/master/pier14/opc-client.
