I came across the Narrative clip/camera online about a year or two ago (originally it was called Memoto). I ordered one in April and it arrived this weekend. Think of it sort of like a trail camera for humans. It is small - less than 2 inches by 2inches, and it has a clip so it can be worn. The camera takes a picture every 30 seconds. You can also double tap it for an immediate photo. You can set it down and it will document what it happening in front of it. These shots are from my sewing room yesterday. I had it set on the bookcase while I was sewing on the binding of a quilt. Then I moved it into the corner when I switched to ironing the binding. I also have documentation on my mowing the yard yesterday. The photos range and its brightness and clarity are not always great but given that it is taking so many - odds are high at least a few of the shots are good. At the end of the day you plug the USB into your computer and it re-charges and downloads the photos.
This would be great for get togethers and parties. Place it somewhere and it will take the pictures of the event. How many times do we get caught up and forget to take pictures?
