  procedural texture as a bump map?

I thought there was a way to do this, so that my wood would have apparent
surface rippling, but I don't seem to be finding it.  I've done "embossing"
before, where I used a BMP of the text, applied it as a bump map, and then as a
texture, to "paint" the object..

I'd like to be able to turn this:
#declare Floor_Texture = texture { pigment { P_WoodGrain18A color_map {
M_Wood18A }}}
                         texture { pigment { P_WoodGrain12A color_map {
M_Wood18B }}}
                         texture { pigment { P_WoodGrain12B color_map {
M_Wood18B }}
                                 }
into apparent disturbance of the normal so that the wood surface does not appear
to be a perfectly flat surface, up close.
