CD/DVD business cards

I have been trying to think of ways to promote myself and i didn't want the obvious as it needs to catch peoples attention. I found the CD business card idea and thought it would be a great way of getting my contact details out in the industry but also my work at the same time. I could even carry one about with me myself so i always have a mini portfolio on me. To make it more special to look at i could design the outer packaging for the cd/business card.
