I've been working on a minimalist deck of cards inspired by dice pips and hexadecimal digits. The assets are available for commercial or noncommercial use (I should probably write a proper LICENSE.TXT about this) since, like, they're just some quick scribbles I did with GIMP and ImageMagick as a proof of concept anyway. Would love your thoughts on this! Can you think of any games that would work better with high contrast cards? Maybe a use for having sixteen ranks instead of thirteen/fourteen?
