cleartech is popularly known for its use in prisons to easily identify contraband. cleartech has also cemented its place in the world of media, including computers, radios, televisions, cds and cd players, keyboards, gaming systems and so much more. i have been a fan of cleartech since i was a kid with my first gameboy color - yes, it was the atomic purple one. in fact, i'm in the process of changing the shells on all my handheld gaming devices to that same translucent purple that i grew up with.
