This is a cool web 2.0 company that. Moo.com makes mini bushiness cards which are customized using pictures from your Flickr photostream. And they're giving away free 10 pack samples for the first 10,000 Flickr Pro users. We selected ours the other night and hope to have them in a week or two, so I'll report in when I get them.
The best part is that the price for 100 cards is only $20 US, which is totally reasonable. I may just have to pick up a bunch, we'll see how the samples come out.
