French artist Nils Guadagnin is paying homage to Back to the Future II in the most appropriate way: by recreating the pink hoverboard Marty McFly, erm, "procures" from a little girl. And hover it does — it even has a nice little bounce when the artist taps it.
Sadly, it probably doesn't have enough lift for anyone to ride it, though Guadagnin certainly didn't skimp on the tech: "Integrated into the board and the plinth is an electromagnetic system which levitates the board. A laser system stabilises the object in the air." Lasers!
Here's a video showing off Guadagnin's board:
