Instant Computerized bookshelf

Danny Gregory writes about a nifty mac tool called Delicious Library that displays your book, movie, music, etc collection. You only need scan the bar code with a "quicktime-supported digital video camera" (e.g. iSight). I will say no more, because the screen shots on Gregory's blog or the product's page say more than I could.

(Save as reference for when I have my own mac)
