VS3D can do this. You simply import the image scaling image brightness to surface height (lighter-higher, darker=lower). Then run a "Peck" (pogo-sitck) path using a V-bit to generate G-Code.
The resulting path will peck deeper where the image is darker.
And since a V-bit is used, the deeper it goes, the larger the diameter circle it makes. And when the holes are filled with black and the surface is polished, the darker parts of the image correspond to bigger black dots on the surface.
