In 2009, I have worked on 2 Quartz Composer projects:
Project MINDTouch - Smart Lab, East London University - an interactive performance piece using Bluetooth and Quartz Composer. I did the QC programming on this; the composition loaded movie clips and applied image effects from a real-time data source over bluetooth.
And while in Vancouver, I did some updates to the QC for the Vancouver International Film Centre with my colleagues at Urban Visuals.
