These are cool! The second one (the lichtenstein house) appears to be a clever implementation of the Hollow Face Illusion

In San Antonio there is a building that appears to be flat(it is a hospital) but of course, it is
quite three dimensional.

I actually had the idea to do something EXACTLY like the geometric shapes that stretch across the interiors of the buildings. I just wish I did. I still just might!

A ma zing stuff. Except that the parking garage in Seattle (been there), though it LOOKS cool, once you take into account that they built it in the middle of the city's historic district at the expence of several buildings on the register (and much to the horror of historians), it looses it's lustre...

wow this got alot of up votes!
over just some building!
i guess im just jealous

Never thought I will get so much votes. But still i'll take it.

Because of this I will like to ask for new plime categories : Architecture, design and-or urban planning.

Loved it.

great find!
