StumbleUpon strikes gold again.
The tile mapper thing is very cool. Looking around that blog, I got stuck for a good thirty minutes! Here's why he started it:
"The original goal of this blog was to document my project to make 2 NPCs for every game I own. Since it began it has become a general RPG blog, focused primarily but far from exclusively on old ?old school? games. But the original purpose of the blog remains and this page exists to help navigate the ever expanding collection of characters created in the project."

An' yeah, he puts a decent amount of thought into each character...

The trick is to have entries and exits at the same points along the edge. Or in the case of the Makers tile game, animal halves at said same points.
