Here's a cool project, that I wish I would've made as a student: a motion detecting paintball sentry gun. Now this is what I call a great idea! This guy, actually made it to work properly, and it also has decent reaction times! Enjoy this demo video!

Here's a funny paintball headshot video clip, including the slow motion and instant replay I can't say that if the guy fakes it or is really knocked out. Anyway it's funny....enjoy this paintball headshot video
