When you hear there's a flashlight that makes people disoriented, and then sick, you just know you won't be able to pick it up at your local Wal Mart. Sadly, only the po-po will have access to the Intelligent Optical Systems flashlight above.
It uses very, very bright LED lights that change color and pulse to blind you and give you a bad case of vomit.
They're going to start testing it soon at Penn State University...want to sign up?
