Here is my near completed Hoverboard display that I started working on over a year ago and just finally got around to get working right.  The board actually uses magnets to achieve levitation just like in the Back to the Future movies. My inspiration came from an instillation piece I saw a couple years ago by an artist named Nils Guadagnin who was able to achieve the same effect. I used an electromagnetic kit that has a laser stabilization technology in it to get the magnets to hover in place.
