Based on the inspiration, a 3/8" = 1' model was built as a proof of concept before the build was approved.
The model was built was made using foam core as a base and a mix or clear straws. When assembling, I ran out of clear straws and ended up using a two hot glue sticks as "rods" in the model. In a "happy accident" it became apparent that the light traveled through the rods much more effectively if they were solid in a fiber-optic effect. This revealed that the final design should have solid rods, or rods that material inside to help catch the light. The design ended up being approved and budgeted.
