Denny, from Sugar Creek Baptist Church in Sugar Land, Texas, put together this set incorporating orbiting circles made from some leftover 4×4 sheets of coroplast. He cut the sheets using a router and a piece of board for the backings.
Once the pieces were cut, he connected them with waxy theatrical rope. He then hung them from the ceiling, lit them, and let the room’s AC do the rest of the work.

This looks cool. Reminds me of “Tron”
