Arcknight has started up a Kickstarter campaign to fund their Roleplaying Maps packs. They’ve already passed their initial goal and then some, so it’s stretch goals for 28 days.
From the campaign:
We created a series of full color, high quality, 11×17 maps that are designed to fit together (typically in pairs) and that are specifically engineered to be rotated and rearranged, creating alternate layouts. Using this technique, you can cater to most types of encounters a party will face in a typical fantasy roleplaying game with fewer total maps scattered about your table.
