So you have all this candy left because only three trick or treaters came to your house.   DON'T EAT IT!  Make some art. This is Candy Art by Eric Millikin.  He used M&M's, Skittles, Goobers and Nerds for Frankenstein's monster.  The whole packages. Wait, I see some Hershey Bars too.

You can see more pictures on his website.  They look good and smell good too!
