For those interested in Architecture and Design, I want to draw your attention to the podcast "99% Invisible".
It is, by far, the best program I have found on all things design-oriented, and is available at:
www.99percentinvisible.org
The show gets its name from the fact that good design and all of the time and effort that go into it are (and in my opinion should be) 99% Invisible. Every object that we encounter, and there are thousands each day, require inumerable decisions and considerations in order to come into existence. The untold hours of thought and effort usually go completely unnoticed by those of us going about our busy day. This show is dedicated to shining a light on the stories behind these objects and taking a moment to help us appreciate the things in our environment that we take for granted.
