Bank Floor Texture

First Rendition 

This will be married together with the Marble shader that Mikey has created. 

Second Rendition - Just a little more visually interesting. The 4-Sided shape in the middle was disregarded for purely being 'Too Much' in the set, so I toned down the amount of things going on whilst still retaining the key visual interest in the circular shapes.

From the screenshot above, the simplicity seems to work better within the context of the set, so we'll stick to our guns on this one...
