Ore minerals and card games

[eller]

So a few weeks ago I was visiting that conference. (Okay, I visited three conferences during the last few weeks, and at least two of them were too many. And then some meetings. Anyway...) The funniest thing I found there was a card game - Authors - featuring ore minerals. Not just a crystal card game but only ore minerals, which was so weirdly specific I (of course) had to buy that thing. Still, I'd like to know, who came up with that particular idea? (And did it sell well?)

By the way, this painting shows Goethite, also an ore mineral. As a reference, I used a piece from my institute's collection. No, I don't work with ore minerals (I'm more the carbonate kind of person LOL), but isn't it nice to know our scientific resources are used so well?
