Billiam Babble on Google +, posted about Inked Adventures, a set of 3d paper dungeon morphs. These sets are available on DriveThru RPG and retail for less than $10.00 a set. In many cases, much less than 10 bucks. You can also check out Inked Adventures link above for free items, support, and errata.
What a deal for a creative and easy way to enhance your dungeon crawl.
For the record, my payday is Friday so sadly I have to wait to order my set.
