So, there exists this thing called PocketMod, which in and of itself is very useful and cool. A pocketmod is basically a miniature 8-page booklet that you construct out of one piece of paper by folding it a certain way and making a single cut; no adhesives necessary. You can learn about it at http://www.pocketmod.com, where they also have a pdf-to-pocketmod converter for making your own.
Why is this so cool? RPG's! As an great example of what you can do with this simple idea, I will turn you over to another blog briefly -- over at RisusMonkey (which is an awesome site, by the way) there exist DungeonWords and WilderWords, both great tools for creativity and both pocketmods. For an even more extreme example, you can get the condensed-and-mostly-complete rules for the Risus RPG in pocketmod format here.
In my next post, I will show you my own evolution to the format. Stay tuned!
