Seeking Advice on Minigame Interface

So, we've been working on a treasure hunt minigame for the ERC Age, and I was hoping to get a professional opinion from you guys on what sort of interface would work best.
The discussion is over here at: http://forum.guildofwriters.com/viewtopic.php?f=76&t=2241&start=0 We've been wondering whether a journal interface would work best, or a holographic interface, or a piece of paper interface...The trick is, the interface needs the capability of having boxes that can be checked and unchecked; furthermore, each of these items would have to hold only the treasure hunt data for the individual player accessing them, and no others.
