Travis Casagrande of McMaster University, Canada, is an engineer who was able to use an electron microscope to carve a (very) tiny gingerbread house that's smaller than a human hair strand
Casagrande used a beam of charged ions to carefully sculpt his gingerbread house, with windows, chimney, Christmas tree, and door on top of a snowman in silicon. He even managed to carve out a Canadian flag as a doormat!
