This is a new DVD resource (release pending) - a new approach to showing how products are created. Four professional Industrial Designers were given the same Design Brief asking them to design a single cup coffee maker. All four Designers were videotaped as they worked, showing how they come up with their ideas and begin to realize them as a final product.

Check it out - there's a 15 minutes preview (available for a limited time) on their website (scroll down to the bottom).
