What if dinosaurs were intelligent beings with burial rights that left no trace of their members. What if the dinosaurs we uncover today are the rejected and banished members of their society? Perhaps socially acceptable tyrannosaurus rexs had long and muscular forearms.
I stumbled upon Jensen Harris's blog and his "The Story of the Ribbon" presentation. This presentation is a wonderful case study of how the Office 2007 ribbon evolved. This long presentation is well worth watching by anyone interested in interface design and/or usability process. The content is great as is the Q&A at the end. (Excuse the "presentation junk".)
