That's right kids! Hoverboards. You've seen them in Back to the Future II, you know you want one, and now they are finally here... sort of.
In 2008, French artist Nils Guadagnin began working on this replica of Marty McFly's hoverboard from the second installment of the BEST time travel series of all time, Robert Zemeckis's Back to the Future. Crealev Company realized an electromagnetic system that levitates the board with a laser system stabilizes the object in mid air.

What's so important about this piece (not underestimating the cool factor) is that it shows the multiple possibilities of how to give sculpture full spatial freedom. Granted, the hoverboard doesn't have the power to actually lift a person from the ground just yet, but it is a very promising step in the right direction.
