This one is actually a blueprint but a funny one. I thought I post the snippet here. If you look at the stepuk's map he has the roads between farmer huts built from gravel, cobble and stonebricks. For this one to work correctly dig your roads one deep in a desired shape from house to house and then use this blueprint, it made my day because of it's simplicity and effect (think laborious road building and this in contrast). Beware if you unleash it with no borders in sight it WILL go haywire
