The "blending into the existing landscape" is solved well - younger 
craters obliterate older ones instead of simply adding up their 
elevation values (like in John Beale's HF-Lab)... but the outer wall 
slopes of craters are too steep!

Oh yes, that would be nice... although I'm mostly occupied with my 
preparations for starting PoVEarth, I sometimes find the time for some 
doodling in between, and creating cratered moons/asteroids would be 
relaxing!

See you in Khyberspace!
