Squares in architecture...

...a double whammy for Abstract Thursday, and to remind you blippers about Derelict Sunday too!
Thanks to Youoregon for the abstract theme today - though mine are mostly rectangles, there is a square view from the blank window behind the spider's webbed one... And it is more or less SOOC, though that should be SOOP, and I had the "cartoon" effect on... which I've never used before ;)
The derelict building is the old army hut that I blipped in March, but from the other side.
