The Photo Album Story Teller is a nifty device that allows you to add voice notes to your physical photos. It works with color coded stickers that are used to identify photos. Place the sticker next to the photo, scan it with the device, and record a message. Come back later and rescan the sticker to hear the note that was recorded.
If writing notes next to photo album photos is too Life 1.0 for you, this could be a fun way to include extra background information with your images. There’s a price to pay for this photo-geekery: the Story Teller costs $100 for the recorder and 500 stickers.
