Brick Nine -- Made from polymortar!
This is one of my more complicated textures; I actually had to use Store/Load operators, which I don't normally like to do!
Also, I figured out how to use normals to give depth and texture to the brick.

However, there are several things I don't like about this texture.
1. There's no way to change the color of the grout (color inbetween the bricks)
2. Thanks to RotoZoom, most of the brick is exactly the same. This doesn't fit into the idea of procedural textures, since the computer can produce its own texture, so, every brick should look different.
