The doorbell rings. I glance out the window and see a Federal Express delivery truck. I open the door, exchange pleasantries with the driver, sign for my package using a nifty industrial-strength PDA, and then watch her scurry down the stairs and back into the truck. As she races away to the next delivery, I take an extra moment to look at the FedEx logo on the side of the truck, as I always do, and smile. Some people smile when they see children playing in a park. Others when they see one of those rare red and-  urple-sky sunsets. I smile when I see good design.
