Cody Brown from Family Worship Center in Carrollton, KY brings us a rock wall on his back wall.
To create this they started by building two 20-foot frames out of some scrap lumber. Then they bent chicken wire into rock-like shapes stapled it over the frames. Then they dropped some paper mache on it. Then they mixed up some greyish brown paint and added sand to the mixture to add texture. After they painted the walls they added some rock wall hand holds to the walls.
They stuck a few LED panels behind the rock walls to light them and added some extra projection on the side walls.
