That actually looks kind of cool. I guess it has some merit as a training tool outside of just 'fun,' but obviously it's waaaaaaaay over-simplifying things. I'd love to see this concept combined with the difficulty and physics of Surgeon Simulator, so when you take the caliper off, it doesn't just disappear. It's swinging there waiting for your clumsy hands to knock into it as you bang on the corroded rotor with a BFH and knock your beer over in the process.
