To answer flyingcrayons orginal question....the system was apparently built by a system integrator (application reseller) in CA called Cyth Systems. I assume as a sales gimick to promote themselves and the NI components they sell. NI apparently has acces to it for their own demos, maybe they gave them the compenents with the understanding they could use it. Anyway, based on what some other individuals have done, it looks like they used way more hardware power than they really needed to do this job, just so they could showcase these particular products. From his description of how it works, I would think it could be done with some much lower price range equipment. Not sure if the cheap Axis camera in the KOP is fast enough, but I'll bet the cRio, labview vision tools, and I/O boards that cam in the KOP could handle this.
