Abstract Thursday, tag AT64

Next: this Thursday's Abstract theme is "Squares in Architecture".
Look closely and get close to SOOC subjects, where straightforward shoot and blip is really this week's minor focus :) Unless you sleep with the trees, this should not be very hard.
Your buildings are built as squares upon squares, and the exteriors and interiors rarely stray from the formula.

Super extra credit for "Circles in Architecture". There are several out there.

Tag will be AT64.
