The blue is actually some Alclad II flip-flop paint, goes from blue to green. Wasn't really impressed with the stuff, actually. It's got very large particles in it, resisted getting shiny, and then doesn't even really change colors very well.
The Playstation was pretty simple, just a peice of plastic card that was the same scale thickness of a PS1, and then I used a hole puncher to cut the little disc door out of some real thin plastic to give it some releif. Glued them together, sanded and carved, and used a sharpie to pick out some details. REALLY simple, but effective.
