Materialize, a free texture generating tool we featured last week has just been open sourced under the GPL 3 license. Materialize enables you to quickly create texture maps such as Normal, Edge, Ambient Occlusion and Height from a single Diffuse map. It was built using the Unity game engine and the author is hoping to see Mac and Linux ports as a result of the open sourcing. The source code is available on Github right here. Simply clone the repository and import into a recent version of Unity game engine to run.
