You won't throw away these business cards

Jeff Nolan has a photo of Steve Wozniak's incredible precision machined biz cards. Check them out on Jeff's blog.

If you want to order similar cards for yourself, go to PlasmaDesign. Prices are ~US$5/card for a batch of 100. My suggestion is not to worry about the cost and instead go with the "field of dreams" approach - If you get such cards, your clients will be so impressed that they will dump you with no-bid contracts.
