Kinda architectural so did anyone else see the feature on Abelardo Morell's work entitled Camera Obscura on CBS Sunday Morning? I saw the exhibit and the lecture when it was here in Chicago at the Art Institute a few years back and it was wonderful. Talk about alternative gear ha ha... If you get a chance to se the piece it is wonderful. Heres a bit of background on the work
