HeroQuest
On the forums at the HQ-Corporation web site, I found pictures of a HeroQuest modular board made from cork and Version 2 from Resin. Both very impressive.
Other pictures
I found these pictures on the S.S.R.G.C. Terrain Builders Guild gallery. It appears that the web site hasn't been updated for two years so I decided to host some copies here in case the site ever goes away. Currently these are hosted without permission.
