Basically just load any random image you want to have on your nightstand/mantle into Photoshop, isolate only one color layer, then bring that over to Illustrator and work as normal to vectorize it.
Actually, it would probably be better to vector first, then split the RGB layers. His approach is a bit different, but really it is a pretty simple application.
RGB works decently well in our televisions, where we can have a pitch black other side, and illuminate white by applying all 3 colors in the same location. Print media prefers to use CMYK, and I could see that being of benefit here. If you will have a white (and illuminated) background, then your black layer could be very thin black acrylic. Or if you enclose in a box to have a black background, you can invert the black layer and edge light in white.
To work around the parallax issues, inset the whole device to restrict available viewing angles. Though at that point you lose the bulk of the nifty factor.
