via Smell-enhanced augmented reality food makes every meal a gourmet feast | DVICE.

Ok this is a little bit strange but could be useful if there is a shortage of food.  You could make crappy unflavored cookies with very little calories but it will make you think you are eating something very tasty filled with tons of calories like a chocolate cake or a Twinkie.  Or maybe if you want a pizza it will make you think you are eating a small round pizza lol.  I don’t know.
