We purchased our CNC router with the specific goal of doing the same type of work we had done previously with plenty of wild and creative textures. At the time there was no one else in the industry doing this type of work with a router.
Needless to say we got the instant attention of the sign industry. Folks wanted to know how they could incorporate these same textures into their work.
The answer is a DVD collection of more than a hundred bitmap textures which we have created.
