Mystery Spot?

Cool...I did not know that the contax g2 could make square negs.

Fascinating! I think the old idea that "a photograph should ASK more questions than it answers", is apropriate and WORKS here. What?, Why??...
And beyond that, simply an excellent presentation. Deserves to be exhibited in a Gallery.
The square format adds a great deal to the overall "viewing experience".

Easy, it was put there for someone to make a cool photo, and you did it!
