This post on Roleplaying Pro reminded me of a gaming tool/accessory that I discovered at the local Wal-Mart the other day. I purchased it, brought it home, and promptly forgot about it until John's post reminded me.
These posters are white but have a very lightly shaded 1/2 inch grid. The grid is easy to spot when you're close but much less noticable when at a distance, and the grid size is perfect for play with minis... each 2x2 section is a perfect one inch square.
I briefly flirted with the idea of creating a few unique battle maps for the last session of our shared game that I'll be running (at least for a while), and I still might. However, I might keep them clean and use them in tandem with Appendix A: Random Dungeon Generation from the first edition DMG. Perhaps we can run a DM-less dungeon romp the next time we only have two people show up for game night...
Regardless of how I use them, I'll post as soon as I get a chance and let everyone know whether they're worth the money. Considering how cheap they were... my guess is that they will have been a worthwhile investment.
