OK. I admit. I am intrigued.
I started basing my buildings on 4"x4" squares, or multiples thereof. Ive always wanted a set of roads that could work with this...and Ive bought a few and even printed out a few dozen full color copies of Toshach's roads (he has nice dirt roads also).
My problem ran into when I wanted Y's and Forks, or Exits (like from a freeway, a Y but with one section being completely straight).
My plan was to print them and mount them on
magnetic sheets from Oriental Trading Co but I havent got there yet. I always get stalled when I feel I am short of perfection: analysis paralysis, as it is.
Here, you have something really, REALLY intriguing to me. I had considered buying that Terrainworks piece myself, but I have zero talent or skill in Photoshop. My existing buildings being on 4"x4" squares may be a problem, but I imagine I can get past it. I am going to follow this with interest, and likely will print a full set out when you've finished. Looking forward to seeing more!
