Wirlem Andrade from TIB São Mateus in São Mateus, Brazil brings us this cool domino looking design.
To create this look, they bought 28 sheets of 10mm styrofoam. They used the sheets as they came; they didn’t cut them. They glued them with styrofoam glue to their back wall. (Once it comes time to remove them, they will heat the glue to get all residue off.)
Then they lit them with 4 LED par cans: Par 64 with 36 LEDs in them.
