Makes Me Wanna Pee More Creatively

This is cool but I heard that someone had worked out a way for an ink jet printer to build human organs. Instead of ink in the cartridges they put a slurry of living cells. The printer spits out a layer of cells and then they pass it over the same "page" again and build a new layer of cells on top of the first layer. Keep doing that while changing the cell pattern with each layer and apparently they can build a heart, or a kidney or whatever chittlin you need. Do you think meat vending machines are in our future?
