I took graphic design in school (so I've seen plenty of business card concepts) and I just wanted to say that's the most creative card I've seen in years! I'd cherish something like that if you gave it to me - no matter how much they cost the impact is definitely worth it. Wow!

You aren't the only one who likes it; it definitely gets noticed. They cost ~$1 (US) in quantity.

The most common question I get is "If I install the chips, what do I get?" Unfortunately, the answer is nothing. There are people who have done that.
