So I just found this mildly addictive program named the Delicious Library. It allows you to use your Isight camera, which is built into my Macbook Pro, to scan bar codes of movies, music, games and books. This builds your library, which is really cool. Perfect for someone like me to be able to marvel over their collection from the road.
Now if I could only combine this with that Slingbox thing, that would be really awesome.
