A little off topic (but not really). I watched a documentary last night called Tim's Vermeer http://sonyclassics.com/timsvermeer/. I thought I would pass it on as a recommendation for anyone interested in optics. The guy (Tim) was obsessed with how Johannes Vermeer was able to paint cinematic quality paintings and set out to prove that he might have used technology (optics) to help him recreate the images. My take on it was the guy (Tim) basically turned himself into a camera with a very simple optical setup. Pretty interesting stuff.
