If you have a stack of old pictures—like, real pictures from your primitive days—they're probably just sitting around collecting dust. Don't you want to move those pictures to the modern age by digitizing 'em? Of course! Shoebox, an iPhone app, can do it for you.
Flickr, who should have jumped on the Instagram filter train earlier, has finally put out an Android app and along with letting you scan photostreams, upload pictures, share photos to other social networks, you can also take filterized pictures. Woot!
