Can we take it further and get custom stickers? My mind turns to corpse manipulation (some Red Dragon / TV show 'Hannibal' type stuff), notes scrawled in blood on walls, quick customization of a basic standard cybernetic arm, etc. Perhaps make this an applied part of the artistry skill?
Side note from IC experience here, perhaps worth noting, falling damage (causing bleeding) doesn't seem to create a sticker. Perhaps by design. But it does leave a new player wondering where they got hurt at so they can create appropriate scars in their @nakeds.
