Here's a really cool thing: mini business cards with your Flickr photos on the back. They're from a London company called moo.com (you can guess the web address, I think...) and they're a) cheap and b) exceptionally high quality. I got a free sample of 10 cards as part of their launch, and will certainly be ordering a pack of 100. Only problem is, I'm not sure I'll be able to bring myself to give any of 'em away ;o)
