Not too long ago, MOO teamed up with Flickr to give away some great freebies: specifically, a pack of 10 MiniCards to the first 10,000 Pro users who signed up. I was fortunate to be one of them, and lo and behold, look what I got in the mail!
This is a relatively hi-rez image. You can almost make out the halftone patterns if you view it at full size.
The quality of the paper is a lightly glossed matte, similar to the packaging I've known for some promo CDs, and the cards themselves are both cute and crisp. I went simple with what I wanted to see on the flipside. I think one of the best parts of it is unlike conventional business cards, you aren't limited to a single design — if you order a pack of 100, you can have a different picture on each card!
And fitting it is that I uploaded the end result back to Flickr. 
I wonder if they'll get into the fortune cookie business.
