Nike's innovation group seems to be on fire! First Sparq and now this. Word and images are surfacing about a vitrual spray, that glows in the dark, and allows you to create your own lines for nightplay. You can color court outlines, the ball, players, anything and be ready to play. The paint disappears after two hours. No word if this is environmentally friendly or not. Apparently it was developed by Nike with designer Pierre Haulot. Very innovative way to take the game late at night. I for one can see some great beach games here.
