From my point of view it's also a way of using the media we have(png, mostly) in the most magical way, you can make the very cool puzzles, but you can also write misterious messages, some of the symbols can fit to write words in the floor(some limits here, but you can manage quite well, anyway I hink this can be fun "What's that, a reverse A or a V?", the human imagination can manage this without breaking I think), meanwhile the players have to test which are the missing letters(I hope you understand what I mean with my horrendous english) to get a password or find the question for a quiz in the wall, it can be also decorative: you move to a room, touch something, and some symbols turn on and others off at the room before, etc. I think this is every GM's dream, a lot of ways for annoy your players in a simple and elegant style! Will purchase next time my players move to an ancient giant temple. Such a great idea, Stephen :D, sorry if I used too much honey on my text!
