So, somebody has invented a tactile touch screen interface where buttons rise out of the flat surface like the Lady of the Lake, and disappear again when you're done with them.

This project at Washington State University is incredibly nifty. Researchers use a 3-D printer to make a bone-like material that can temporarily do the job of bone, while serving as a scaffold for new bone to grow on. Over time, it dissolves safely.
