I happened across this today and was amazed. The photo is pretty ordinary, and the set up looks pretty ordinary but watch the video and see the depth of the setup. Pretty cool, takes a different mind I think.
Brilliant! I wish I had the creativity to do this, but more importantly, I wish I had the commitment to follow through till I finish. :) There are a lot of interesting stuff on that website.
