Come to think of it. would there be interest in a device that would allow inspection with at least normal and UV light from different angles? (Raking light, which is useful for seeing gloss and any ink with some decent dimensionality to it )
I built a prototype of a device very similar a few years ago, and the guy I did it for is thinking of revisiting that device. I'm probably going to be buying materials and the LEDs to light it in the next month or two and making both wouldn't be hard.
