One of The Code Trip sponsors, InnerWorkings, has teamed up to have a coding challenge for developers. This is open to everyone to participate. The winner gets an annual subscription to InnerWorkings as well as an XBOX 360 game console.

I really do believe in their product as it is a unique learning experience from what we traditionally have (i.e., lab manuals with step-by-step instructions). They have a wide catalog of topics including ASP.NET, WCF, WPF, Silverlight, CSS, etc. for organizations to choose from. You really need to check them...
