From their announcement:
Hotz Mats: Moonscape game mats are now available for ordering. The Moonscape game mats are available with or without hexes/squares, and are also available with or without airbrushed crater art. These mats are handcrafted and can be customized to some extent: more or fewer craters can be added; different size craters can be added, etc. The hexes/squares are not merely printed onto the mat, but instead are integrated with the crater artwork so the craters become part of your game, not just a great looking backdrop.
