A friend of mine has started a new business - card-shark.de. Basically it is about trick playing cards for magicians - those type of cards that have two diffent card types and values of the front side, a totally different back etc.
It's actually pretty cool and there seems to be a rather big demand. And you can also configure your own personal trick/magic cards with a nice rich internet application (click on "Online Card-Builder) in the navigation.
