Nathan Thomas from Berean Church in Pleasant Hill, IA brings us this cool pyramid structure.
They took corrugated plastic (8×4 sheets) that were $11 each and cut them into 3 different sized strips (3″ 4.5″ 6″). They used gaffing tape and small “t” pins to put them on the wall. They also cut 45 degree angles on the ends, then used 14 LED color bars (about $150 each) to light it up.
The materials, minus lights, cost $120.
