Moo Business Cards - giveaway!

I am mesmerized by Moo Business Cards - have you seen them??  ah-mazing.

The cool thing about Moo is that you can get a SET of cards - like the cards don't have to all be the same.  It's called Printfinity, and it's such a genius idea - - this video explains it all and shows some fun examples:

The problem:  I can't decide!  One option - - have an image of a different popular project of mine on the back, kind of like these photos"

Another option - do something random and unexpected, like cassette tapes, on the back.

I've also considered drawing out a puzzle or my logo image or something and then dividing the main image into 6 or so small pieces of the image, so you have to collect all 6 cards to put it together.

Or another idea is a unique link on the back of cards - like access to a special project or something, and come up with half a dozen of those so you'll want to collect them all.

Or what about using the MiniCards and twine, like a tag?

And then there's the option to get sticker business cards - how cool is that?!

So, recap, business cards I'm think of -
--different project photo on each one
--randomness - cassette tape, etc
--puzzle/logo and you collect all 6 to put the image together
--unique link on the back to a secret blog page
--minicard to look like a tag
--sticker, so you can stick it to something

If you were at a blog conference with me, which would you like to receive?  If you were a blogger, which would you like to give out?  I just can't decide so I thought I'd ask for opinions.

Also, it's giveaway time!  3 winners will each get a set of 50 Classic Business Cards.  To enter, use Rafflecopter below:
