I'm thinking at the moment: Why aren't more character sheets designed to be folded? If you have a character sheet that can be folded, this means that it could be reconfigured during play to display different information, depending on what is happening in the game. You could have a section for combat stuff, or out of combat stuff, or relationship information or whatever your game calls for, and have it display two bits of character info together while avoiding the stuff that is currently irrelevant.
For example, I was playing around with designing a character sheet for a D&D character
. On that sheet, you have all your non-combat info (skills, feats, rituals, etc) on two adjacent panels that can be displayed when not in a fight. And all your combat powers are on a separate section, that can be opened up on your turn and folded away when not in a fight. And your out-of-turn but in combat stuff is on a flap that can be folded over when you're attacked easily enough. (For a different character, I might have rearranged the At-Will/Encounter/Standard setup of powers to be based on action type so that you can have the Immediate Action flap open with your AC and HP information.)
That's just using a straightforward trifold brochure layout to make a character sheet, and it gives you several possible configuration for your data. So you can use the sheet in different ways depending on what's happening in game. For a game focused on something else, the different information on each flap might be entirely different. But with that brochure, you can present information A, B, C and X, Y, Z in a variety of ways: A and X at the same time, or C and Z together or A, B and C or AB but no C, etc.
One classic Paranoia sheet had all you public information on one pice, which was folded over a second part that had all your secret information. That's some good design, there, because it considers what the game is about (hiding secrets from your friends) and uses the sheet to facilitate that. A few Larp projects I did had similar concepts in mind for the layout
: you print the sheet two sided and fold it in half like a booklet. Then all your secret motivations and information can be hidden while your public info is on the outside.
