I discovered the game Hex when I spent a semester in Australia my senior year of college. Taking the things I learned building Minesweeper, I thought I'd see how far I could get with Hex. I'm pretty happy with the results. (As with my first post of Minesweeper, this is a work in progress.)
I had a lot of fun with DataTemplates and DataTriggers. I also made my first jump into storyboards. Fun stuff.
