"Live Oak Friends Meeting House"
"The Light Inside"
James Turrell is a Quaker artist who uses light in his works. He is not a video artist, but I thought his works (coming from a religious perspective) would be relevant to our discussion. I found his works through Art 21, in the special on Spirituality. Again, Christian artists are hard to come by, but it's worth checking out to see the artists of other religions, and their approach to incorporating their faith (or lack of it) into their art.
