Allthough I feel my project is far from some of those posted here I nontheless want to show you what my artist and me are currently working on. Its a german card game called Doppelkopf, but we plan to add more card games in the future and also add a multiplayer mode. What you cant see is that camera and cards use animations to fade nicely to their positions, but I am going to create a video within the next days.
I use the latest SVN version (still having a memory bug in debug, I posted in the forums). We will consider to change the design later, but the default layout is sufficient for now. It's really a great gui!
