I am not quite sure what you are looking for.
At Github or CodePlex you'll find plenty of software projects to play with.
Hope this helps.

http://www.visualstudio.com/en-us/products/visual-studio-express-vs is probably what you are looking for. About 1/2 way down the page you'll find the information for Team Foundation Server 2013 Express with downloads. Also, if you are just looking to use TFS in a hosted environment, www.visualstudio.com/products/visual-studio-online-basic-vs is free for up to 5 users.
