This is the last call for the Geomorphic Beermats Kickstarter which ends in about 3 hours. I've really enjoyed this campaign. Just one week ago I hadn't even considered it as a campaign. The beermats were just a little test print-run. Now it looks like I'm going to be ordering over 25,000 of the things!
My last sample maps are some of some miniature-scaled sewers. They're pretty similar to the mines I posted earlier today, but show another potential use for the mats.
