The first idea is to have a small sound recorder hidden under a coffee table in a coffee shop. Every fifteen minutes the sound recorder records fifteen seconds of sound and uploads it to twitter. The idea is that every hour or half an hour or fifteen minutes someone new is sitting at the table and having a random or meaningful conversation. With fifteen seconds recorded we can have a rough idea of what is going on and in a way get a snapshot into someone’s daily life.

Put a touch sensor in your hand for a day and every time you touch something it tweets. The idea is that you become aware of the interactions that you have everyday. And also of the times when those interactions occur. Maybe you can see patterns from everyday and understand more about yourself, maybe nothing significant actually happens and you don’t find anything interesting. I think its worth the experiment though.

More on the business side, something that could be interesting to make is an app that tweets every time a cash register opens. This way, the owner can keep better track of what is going on in his business. Maybe he can get useful information of unusual movement like the register opening at 3:00 AM or opening too much at a particular time.
