I'm aware that there was an absolute craze for geomorphs, with designs splashed across the blogs and forums last year. I still marvel at the layouts created by Dave's Mapper, and at all of the people willing to draw geomorphs by hand and share them with the world.
After shunning the humble geomorph for many years, now, as a back-burner project, I have decided to dabble in this tesselatory madness! Although, it'll probably be 100 years until I pull together enough to make a playable set.
