Space-Time Distortion Cloaking Design

This is a new and very interesting way of approaching cloaking. Instead of trying to hide yourself in space, instead hide yourself in time! As cool as this idea is though, I must point out how incredibly impractical this kind of system would probably be. You need to somehow get this light slowing machine between you and the viewer without them seeing it, and to get any practical amount of cloaking time it'd need to be super deep. (With light going 30 mph, it'd have to be half a mile thick to get 60 sec of cloaking). Still, its pretty bad ass in theory.
