Finding your car in a crowded parking lot can be a nightmare. Mac Funamizu has the perfect solution. His concept design, the Fireworks Locator System, uses holographic images of fireworks which is projected above the car when the emitter attached to the top of the car is triggered by a remote.
This could be a great idea, although perhaps different colors or firework signatures need to be developed to prevent an abundance of fireworks holograms set off at the same time from causing even more confusion.
