You know those 2D pictures that when you look at them from a certain distance/angle they suddenly look like a 3D scene? I was wondering if that has ever been tried with CP art? I had this idea of a CP with the underside of the buttons, wiring, etc, all drawn on the CP art itself to make it look like there is no top panel; just an open space into the guts of the CP.
Dunno if I'll try it, but was wondering if it's ever been done?
