Mark of CrystalMinds has finished his beta version of Settlers of Catan designed for a multi-touch computer system. You know, the kind where you play by dragging and moving pieces around on a flat horizontal screen.

He welcomes beta testers, but you have to have the hardware to try it out. When i asked what that meant, he pointed me here, which didn’t answer the question, but puts his work into context. You can see example applications here.
