What's your new medium?

When looking around at materials for new projects, I have come across some interesting concepts, but here is one that I think is fabulous! Images on Potatoes! Not only is it interesting because it is a uniuqe medium, but I love it because over time it changes. Potatoes start to shrivel or sprout, so the art itself changes over time. Actually, the art itself, could techincally "give birth" to a hill of new art pieces. And no doubt they would be a real "chip" off the old block.

I also would love to know more about the process. The images seem to be digital, perhaps printed directly on the potatoe or applied in some manner.
