Why we don't have smaller houses

A great article from this Sunday's New York Times. Why can't we build smaller houses? The wonderful Sarah Susanka is one of the commenters.

Marvin's New Product Viewer

I have often used Marvin products for custom projects. Marvin has just put a great 360 degree product viewer on their website. This viewer lets you look at any aspect of their windows and doors from any angle and you can zoom out or in. I applaud manufacturer's websites that make their offerings easy to understand, specify, and interact with online. I'd like to make a category for this kind of thing but what do you call it? Helpful product viewers?
