Laser letters in the sky

The Dirt posted a video from a Japanese company showing a portable unit that uses lasers to create plasma images in the air above the unit. The current intent is that this unit could be mounted on a vehicle which could be deployed during emergencies to "draw" messages in the air in places where a sign could not. Non-emergency uses in parks could be interesting too.

But, for geodesigners,the implications are slightly different. Watch the video (below) and ask yourself how it would look if a future generation of the unit were mounted sideways and cast images over an adjacent landscape. Could the designer of a new park use this visualize different shapes for potential landforms? Could it help the public visualize alternative scenarios?
