Last year i visited Ghibli museum in Japan and as tickets they give you really nice cardboard tickets with a small pice of cinema film in it and if you look against some light source you can see what is on that film so i am designing and 3d printed stand for it that will have some leds to illuminate it when you slide it into it so it will have a microswitch that ticket itself triggers and it will be connected to usb for power so electronicly it will be very simple just usb connector, microswitch, and leds with some resistor and hopefully nice printed case. If it will look nice i will put it on thingverse or something.
