From the post:
Blue Dungeon Tiles reached its funding goal this past weekend and to thank the gaming community and backers, Red Kobold Games has released a second free promo: Tech Decor 1. These are items you can print on cardstock and cut out for use on your current 1"=5' scale battlemats, map tiles and deck plans. There are useful for Steampunk, Sci-Fi, and Post Apocalyptic gaming genres.
