Ignite Seattle! offers Great Program Ideas

Even if you aren’t a geek, techie or maker, you’ll find reading about and viewing photos of the first Ignite Seattle! event fascinating. The idea of combining an event such as a popsicle bridge building contest with talks by techies could be easily adapted for library programs.
From the about page of Ignite Seattle.
Ignite is a series of geek nights in Seattle. It is hosted by Brady Forrest of O’Reilly Radar and Bre Pettis of Make. The nights combine a Make contest (like a popsicle bridge-building contest) and a series of fast-paced, short-form tech talks. The first Ignite was a great success with 17 bridge-building teams, 25 speakers, and 250+ attendees.
