The simplest way I can think of would be to compose the transparency and
RGB images into a single RGBA image, then uv map it onto a ring shaped
mesh.

The only other idea I had is rather crazed.  Create a bunch of colour_maps
and then combine them together with a pigment_map using wood pattern for
them all.
