I like this... it's a really cool idea. That calendar is nifty! The lighting seems a bit off to me though. The photo could also do with a bit more tonal depth.
Cool shot, I like it, whatever it is :-) I find it a little too dark down the bottom right area but that doesn't affect it too much. Everything is in focus and the choice to go B&W was good -8.
This is just a bizarre image, that I love a lot. It is esoteric in a scientific way, and the circles and lines reflect the challenge theme of pi well. Well done!
