You may have noticed the playing surface we used on our X- Wing game. It is actually a banner printed from images taken by Hubble. A company named Banners on the Cheap (www.bannersonthecheap.com) prints banners using all sorts of images. They even make roleplaying maps. The 4' x 4' banners I purchased cost $22 plus about $6 for shipping. I have ordered a total of four of these play mats. So far my experience with this company has been very positive and I highly recommend them.
