I read this after taking the tour. It's about the concept and creation of the Segway Human Trasporter. I found it absolutely facinating. The title is Code Name Ginger. The first concept HT was called Fred. Hence Fred and Ginger (Rogers and Astaire). Here's an Amazon link to find out more: http://www.amazon.com/exec/obidos/A...62/sr=2-1/ref=pd_ka_b_2_1/102-3849971-5780145 Maybe this is geeky but I really like finding out 'behind the scenes' stuff and this book really did it for me!
