Inspired by various side lit, etched signs, I wondered what it would look like if there were multiple panels with stacked imagery lit by changing color patterns.

Current Version (v2)

This version used a fixed frame to hold strips of side emitting LEDs. It retained the press fit bracket.

Upcoming improvements (v3)

The next version will leverage a stack of custom PCBs with side emitting LEDs. The panels will be bolted together with washers ensuring spacing. The entire assembly is designed to fit within the volume of the shadow box.

Original (v1)

This version used a press fit bracket to hold the panels together. it was effective, but subject to easy breakage and prevented any cleaning of trapped dust with compressed air. Taping the LED strips on was good for rapid prototyping but they did not stay in place over time.
