Techcrunch.com beschreibt den Moo-Service:

Moo is an online printing service that now lets you turn your Flickr photos into small business cards. After logging in to your Flickr account, there’s a nice drag, drop and crop interface. The end result are thick, glossy cards that are long and narrow and about half the size of regular cards. The company will send you 100 of them for $20 and Flickr Pro users get 10 extra cards for free.

Also Visitenkarten mit Flickr-Fotos bedrucken. Thats it.
