Open source projects are a great barometer of the tech industry. While companies take time to establish themselves and venture capitalists take months to decide where to place their bets, open source software takes just one programmer and a public repository. If the programmer has a fast Internet connection and the project is small, it only takes seconds for the world to see yet another possible branch in technology's evolution.
We poked around the repositories to find newer projects that are gaining a real following. By no means complete, this collection contains examples of projects that span the major areas of interest blooming in the open source community today. Grab some code and give them a try.
