Greg Campbell from Lakeshore Christian Church in Antioch, TN brings us these window panes with gaps in between.
They had some window frames left over when they remodeled an old retail space. They repurposed them as a stage design element. They spray painted the window frames light gray and added fluorescent lighting diffusers to some of the open frames. (Cut to size and in random intervals.) They used hot glue to attach the diffusers to the frames.
Then they suspended each frame from the lighting raceways with airline cable and lit them with LED cans.
