Take all of those chewed up pencil stubs and put them to good use with the Pencil Printer.($TBA) This ingenious electronic takes your old pencil stubs and separates the graphite from the pencil to use it for ink in the printer. The printer also uses the erasers to erase things you have printed as well. While the exact method of how this printer works is not really clear, but the idea is great and hopefully it will be on the market soon.
