• Fate dice
• Poker chips for fate points
• Index cards for NPCs. Since I often build plots as characters, I also use the cards for that.
• 3x5 Post-It notes for on-the-fly aspects, which I can then stick to the relevant character. I also have a smaller pad of Post-Its for boosts.
• I have one of those Noteboard fold-up whiteboards (http://thenoteboard.com/
), but I have yet to actually use it.
