Abstract Thursday - Squares in Architecture

The main idea is to get close to those squares and ninety degree angles, in architecture so that with continued viewing the perception takes on a different aspect. In other words, without more information the abstract becomes a true abstract. "And" with little or no treatment, so as close to SOOC as possible. This is my living room ceiling area.

Next week's theme will be "Fall". This can commemorate the first day of fall, but still remaining abstract-true to the challenge. Or can it can depict what happened when you tripped and fell while blipping? Some may want to consider the fall of civilization as we know it, maybe an apocalyptic bent.
I like that the freedom of our challenge can always fall wherever you want it to, with the theme being a nudge into familiar territory or experimentation. Tag this AT65.

I include a link to photographer Bruce Davidson's work, just to share.
