Catherine Woolaway from First Church of the Nazarene in Decatur, IL brings us this simple use of gobos.
They bought Celestial glass colored gobo’s from Rosco and used them in two Chauvet Legend 550’s mounted in front of the stage on light bars. You can check out these gobos here: http://www.rosco.com/us/gobos/index.cfm?goboTypeID=2&categoryID=20&action=browse
Then they added four par cans on each side gelled with congo blue. On their dark gray wall it gave a nice glow.
