Andrew Hunt and his crew from Blue Ridge Community Church in Forest, VA brings us this great alternative to the pit ball concept.
They bought a bunch of half-ball styrofoam balls online. This kept them from having to cut each one in half. (You can easily get them at your local craft store or save money online.)
Andrew had already drawn them up in Sketchup so they knew the spacing before starting. They marked off the spacing on some 4×16 panels and used a chalk line using Irwin Dust-Off chalk to make the grid. They applied Liquid Nails to the back of each piece of styrofoam and centered each piece at the cross hairs of chalk. Once they were all applied, they used our eyes to make small alignment tweaks. Then they dusted off the chalk. They let them sit overnight and hung them the following day.
The 4x16s are recognizable as they’ve used them for several other designs in the past. They like to recycle as much as they can. They painted them black and used them as a structure for the styrofoam.
Cool idea: Imagine projection on these using smaller balls. Cool LED wall alternative.
