This was a really close call. If I could declare winners in two categories, I would.
And the winner is....
(drumroll)....
I really love the use of geometry here - so many repeating patterns and shapes, and it's quite easy to lose yourself in it and not think about what it actually is (a metal picnic table setup) but also come back and recognize the object, then lose yourself in the abstraction again.
I have a runner-up.

I think this fulfilled the assignment the best of all the entries. I like the use of repetition of pattern from the out-of-view light source (Venetian window shade?) that is picked up and distorted by the glass and its shadow. However, I can't in good conscience give the win to a non-subscriber - it's not fair to those who support the site.
So congrats, MattKing, you're the winner and the chooser of our next MSA theme! And congrats to everyone for submitting work. This was a tough challenge and I really appreciate all the effort that went in to each entry. Keep shooting and keep thinking!
