I'm very pleased with my Moo cards, the personalisation they provide is great.

These are my 5 favourite ones from the last batch I got. 2 of them are of my most viewed images on flickr, and the others are personal favourites, from The Botanical Gardens in Dublin, full moon over Sandymount Beach, and a composition from a breakfast in first Dublin flat.

They convey a human element of business cards in the best possible way, really, which most business cards lack. You don't have to have a flickr-account to get them, you can use images from your off-line collection as well, no problem.
