Launching model rockets was great fun as a kid.  But now a near generation of rocket launchers has emerged, and their toys have grow up substantially. This video is sure to open a few eyes. With gorgeous photos, infectious glee and just a whiff of danger.

“Scary-smart” is a phrase that comes up in coverage of Steve Jurvetson. In his work at Draper Fisher Jurvetson, he’s taken early and influential positions on some world-changing tech ideas — such as the viral marketing of Hotmail. Now, he’s looking forward into nanotech and synthetic life, and the Valley is looking over his shoulder.

He’s a passionate advocate of new thinking on technology — especially on his thoughtful and funny blog, the J Curve. His massive Flickr set documents his many passions — speaking at conferences, meeting like-minded geeks, shooting off rockets.
