3d text on a sphere

hi, maybe this has been asked before (in fact, I think it’s not very original ^^), but I need to stick some 3D text on the surface of a sphere. it should be a model, not abump map.

something like this:

how would you proceed?

maybe there’a a way to extrude a grayscale map to true model?
or maybe Blender can adapt a model to the surface of another (i.e. model text then drop it on the sphere’s surface) ?

thanks for any advice you would post …

Try warp tool. http://wiki.blender.org/index.php/Manual/Basic_Mesh_Tools#Warp_Tool

many thanks!

I have not used it myself, but I think you can use a displacement map as well. But as I said, I haven’t used it, so I’m not sure if it works.
