Ceiling? Floor? Walls?

I really like the look of this photo.

The strong angled shapes, the strong blacks and whites and the symmetry presented all very well.

Tom,

Thanks for leaving kind words to my photo. This pic of yours is great. I like the title and the composition is unusual but very convinsing as it brings me to the inner world of thinking, figuring out the perspective as you have put in the title. I guess in a structural confinement like this presence it is akin to the human mind. What you see and what you think is all individual. A great photo that allows every interpretation of value. Thank you.
