http://www.xdsoft.com/ this is the best one I have found..it does about everything and is updated a TON. As to what I was talking about before with randomness...I was wondering about the whole seed thing. This method of land generation has been in games since back in the games of Mule on the c-64. Its popular b/c if you change the seed from 500 to 900 and then back to 500 then 500 will stay the same. What the problem is, is that the worlds dont appear very diverse after you visit the first couple 100. I was just wondering if you found an actual random command like 6*(rnd)+1 for the formula modeler...I bet you could use something like that to generate some cool stuff.
