I have made this and was really inspired by a pirate and gem theme. I love a minimalist style for any project I work on including this one. It is a set of 54 playing cards excluding the back. The back (top left) is where I got most of the feel of the cards from. I did this purely for fun. If I were to have an audience for this it would be for anyone that is a fan of techno or even just loves a very simple type of design.
