I was trying to duplicate the wilderness terrain glitch ( http://www.youtube.com/watch?v=W2z1LNIpQfk http://www.youtube.com/watch?v=v00tF0OOqXo ) and got sort of successful:

As I tried to experiment with it more and more it just started outright crashing on me, so I sought another way to push Daggerfall's terrain generation system.

I talked about it on the DaggerXL IRC channel and SuperSnake (or python+) recommended http://andux.svatopluk.com/. I checked it out and the heightmap of Daggerfall it created had https://dl.dropbox.com/u/32146097/The%20two%20mountains%20of%20the%20Illiac%20Bay.jpg, each one cell large.

I decided to check the one I can get to most easily out and http://www.youtube.com/watch?v=e_n6XJNRok8.
