Pixel donation box

This year I am hoping that my show has progressed far enough to consider collecting for charity. With this in mind I have made a donation box that will also be part of the display.

The front panel (which will display the charity name) contains four nodes which are four sections of a 30/10 12v strip. On top of this is a layer of perspex with a square of tin foil behind this to act as a reflector. This then has a wooden panel behind it for added security.
The money slot is lined with a box made from perspex which has another 30/10 strip with a strip of tin foil to help even out the light.
