Specifically, one way to make your cards stand out is by incorporating that oh-so-familiar Google logo. Or an actual screen-captured Google search result featuring your company. Or something along those lines. See the post for some clever examples.
Neat! I haven't used (or needed) business cards for years, but I can definitely appreciate this approach. Hand a card like this to someone and you're sure to get a smile, if not a permanent place on a desk or bulletin board. Which is exactly what you want from a business card, right?
