I recently started an Open Source club at my school, and one of the key aspects of the club is that I (along with a few others) give quick tech talks. I found that it took far too long to whip up a short slideshow, so I wrote this. Its entire purpose is to allow you to get something presentable and interactive out quickly.
It's sort of a two-birds type deal because we'll be actively working on this project through the club :)
I'd love to hear your feedback!
