I'm always wondering what to do with my digital photos. I never seem to get around to printing them out, so they just sit on flickr or my hard drive, waiting for me to get around to them.
But a friend just turned me on to MOO. This site lets you upload your photos or pull them from your Flickr gallery, or another source, and make personalized note or business cards. You specify the image and the wording (up to 6 lines of text) & they print them up for you. The cards are 100mmx100mm and cost $24.99 for a set of 12 (plus shipping).
