The photography mechanics in Sindome are already pretty robust, but it would be pretty cool if you could write a note on a photograph after you print it out. Either on the bottom (assuming they are like Poloroids) or maybe on the back?
At the most mundane this would let you to date the photo (allowing for something of a time capsule, assuming the item lasts that long) and at worst you could write a threatening message on it before sliding it under some chum's door or pinning it up somewhere.
Thoughts?
