I happened to see his show in Seattle and thought the visuals were cool and looked up who was behind it, good job!
Skrillex Summer Tour 2011 dev pt.2 from Sensory Sync on Vimeo.
this is the setup, designed and conceived by Sensory Sync for the Skrillex Summer Tour 2011
we built / programmed a custom media server using Touch Designer
we also have a custom USB to DMX box used to send data to the moving LED panels – both the visuals and DMX come from a single laptop
the system is designed as a live performance VJ setup and the majority of control via MIDI controller – if you notice, there is a foot pedal to drive the strobe effect 
the system goes live June 19th info here:
