Dyson's Random Morph Map
I'm a little behind the curve on this one (the Ruminator beat me to the punch), but Rob Lang over at the Free RPG Blog put together a handy-dandy little web-page that randomizes the totally awesome geomorphs being produced by Dyson (of A Character For Every Game fame). I absolutely adore Dyson's map work. His style totally resonates with me. His maps evoke an old-school aesthetic, are easy to read, and best of all are bursting with ideas for cool encounters. These particular geomorphs do what I didn't think was previously possible... they incorporate multi-level ideas on a two-dimensional map in such a way as to seem totally natural.
If I get the time (and I'm not sure when I will), I may try to expand on Rob's script. It seems to me that the only thing missing is the ability to rotate or flip the geomorphs. I also can't wait to see what this all looks like when Dyson completes his set (as of today, he's on geomorph #39). At 100, there's bound to be a staggering variety.
This all makes me want to do another solo dungeon-crawl. I've done some with Mythic using my AD&D Dungeon Masters Guide (or OSRIC depending on my whim). But the dungeons produced seem to lack coherence that I hope geomorphs could provide.
