Stating the obvious
I'm not covering any ground breaking news here, just pointing out the obvious. Have you guy's noticed how much Love for Triangles there's been lately? Don't get me wrong, I love triangles, much more than circles (even though that is the most perfect shape).
I always like to compare architecture to fashion. It's easy to see the mindset of an era by looking at their clothing. I know today's era is probably I.M. PEI's favorite. All hale, the decade of the equilateral, isosceles and scalene triangle.
