I went to Ignite Ann Arbor last night. Ignite is like a cross between a poetry slam and a geek knowledge dump. Each speaker comes with 20 slides, which advance automatically after 15 seconds, and has 5 minutes to speak.
The topics ranged from “Keeping Things in Balance: Classic Visual Ratios” (an excellent talk which taught me about Fibonacci ratios in web design) to “Real-time NOAA weather satellite imagery reception from home” (which was mind bottling – with a scanner, an antenna and some free software you can grab data from a satellite).
I highly recommend going to an Ignite event, if you have one in your town. Unfortunately the next one in Ann Arbor isn’t for another 4 months, but they’re everywhere. Check out the Ignite website for more details.
