Stephen Hawking's new (and #1 selling on Amazon) book used a Flame image as its primary design element. Flame is Open Source (see this documentary on YouTube) and the basis for the Electric Sheep collective/evolving screen-saver. You can download software and design your own Flames.
I had a fantastic time at Gnomedex. The speakers were interesting and diverse, and my talk got a warm reception. We were treated well by the staff, and the whole event ran smoothly. Congrats to Chris, Imei, Kat and the the whole team!
The connections made there are still resonating. And I still have a pile of follow-up emails to send!
