I am not sure how Tom Aust did the *physical* transition (mesh or 
isosurface, combining the step stone and the ground) but the texture 
probably involves a slope pattern with altitude control.

Building a mesh is best done with an adequate modeller like Wings3D; an 
isosurface can be made very realistic-looking but is also fairly complex 
to build, and slow(er) to render.
