Van Metschke at South Hills Church in Corona, California brings us these floating squares. (Originally from June 2012)
To create the set, they started with 2×3 black Coroplast panels. They added crumpled newspaper to the panels using 3M Super77 spray-on adhesive. They stapled the panels to their wall, but they could easily be hung using hooks. Then they lit the panels with LED lights from the floor.
Scott Anderson and the team at Crossroads Church in Corona, CA supplied the panels.
Plus, check out their home-made music stand blinders.
