Feeling a little bummed about your holiday gifts — or lack thereof? Cheer yourself up by snagging your spot in line for a Mercier-Jones Hovercraft ($TBA). This ambitious craft — which is still in development, so put your Amex black cards away — features sportscar looks, a patent-pending directional control system for unprecedented maneuverability, carbon fiber and metal alloy construction, a single gasoline engine that supplies electricity to the three electric motors, and open-air, tandem sport seating for two. Arriving... whenever they're finished with it.
