PCB Display Case With Overhead WLED Lighting

PCBs often don't work out, however, they can be quite beautiful. This PCB Display case is laser cut out of 1/4 inch MDF and a hardboard backing, with overhead LED lighting controlled by a Wemos D1 mini ESP8266 board, and WLED firmware.

WLED is available here: https://github.com/Aircoookie/WLED and is an amazing piece of software for addressable LED automation and control. The same concept could be applied to any sort of display case/shadow box, which could be a great way to get the same sort of effect without a laser cutter or complicated mechanical assembly.
