This is so uber-dorky and utterly video thing I can't believe I missed it before:
Introducing the RGB guitar solo. Viditar is Livid's pioneering custom made video instrument for real-time video expression and performance. Viditar's integrated hardware and software takes video performance away from the computer and onto the stage. Generate high quality real-time video performances by combining video triggering, scratching, source mixing, and live camera manipulation, to give you total control over hundreds of effects and thousands of media files.
Evidently they custom build these things, so you probably have to pay big bucks for the privelage of getting made fun of for wearing one. Livid does make a tabletop video controller called the tactic that gets big points for being partially made of wood.
Thanks to Skye for initially sending me a link to the Tactic
