I am slowly but surely working on a new project called Memory Game. It is an attempt to create something utilizing a bunch of the newest .Net technologies including WPF, CompositeWPF (Prism), Moq, MbUnit, etc. It should also be a good starting point for other ports (Windows Mobile, Silverlight, etc.) and should be a good learning experience for me as well.
It is currently hosted on codeplex.com and will be open source, but until the source is somewhat stable I'm not going to bother linking to it. I just wanted to post something to show I am still kickin'. I hope once the codebase is at least somewhat respectable to get some feedback and insights from other devs out there.
