No matter what happens in the raging format wars, Blu-ray may always have an exit strategy--in laser pointers, if not videos.
The "Sonar Series" of pointers from Wicked Lasers actually uses Blu-ray technology (blue laser diodes) in its beams, which are so intense that they approach infrared waves, according to BornRich. The result is a "supernatural fluorescent effect" emitted from its aircraft-grade aluminum casing, the company claims.
Unfortunately for consumers, the price is equally paranormal at $2,000. Maybe you can find a used one at a roadside stand near Roswell.
