Started back in 2008, DemoCamp is an event that brings together developers, creatives, entrepreneurs and investors to share what they've been working on and to find others in the community interested in similar topics. For presenters, it's a great way to get feedback on what you're building from peers and the community, all in an informal setting.

The rules for DemoCamp are simple: ten minutes to demo real, working products, followed by a few minutes for questions, and no slides allowed.
