If you came to my house for Halloween this year the first thing you noticed was 18 inch tall green vampire marshmallows moving around on a 8 foot tall screen hung from the garage door. The next thing you noticed was that a laser assault rifle was placed into your hands and you were commanded to kill Marshie for candy. Ok, by laser assault rifle I mean a laser pointer put into a bunch of PVC, but it looked pretty cool. When a dot appeared on the screen it was detected by my iSight camera and Marshie exploded. If you're interested there are more details including a movie posted here.
