The OSL Mason is an OSL script (thus it does not work with GPU rendering in Cycles) coming along with 30 ready-made and instatly usable procedural brick materials. The shader itself works with any renderer compatible with OSL, eg. Cycles, VRay and Arnold. The materials are different settings for the shader implemented using Cycles shader nodes.
The source for the shader is here.
