I've been using heatsinks (the finned ones from mobos mostly) as
business card holders, I have one at my desk at work, one in the garage and will start asking friends and family about putting them out for me.
It's pretty straight forward, put one card on the outer face with tape or glue and then fill in between the fins with cards. Looks really cool and kinda gives a clue to people about what I'm (we're) about before they even read the card.
I haven't figured out the pic feature yet, but I will give it a try when I have some time.
