Nice story on HP’s CoolTown project, in which users “paint the air” with messages about a given geolocation or object, keying it to a location or a unique ID. When your computer comes in range of (or is queried about) a spot on earth or a bit of stuff, it consults the CoolTown database and retreives others’ annotations — “I was here but now I’m gone. Those who knew me knew me well, those who don’t can get bent;” “Be right back – Godot;” “The food at this restaurant is inedible trash, get drunk instead;” etc.LinkDiscuss (Thanks, Muirwylde!)
