A team on animators and computer engineers has created a wind tunnel which uses light instead of, well, wind.
The video recreates the path of air as it moves around a vehicle, in stunning paths of electric light.

It was created by the Marshmallow Laser Feast visual effects crew, who used the £700,000 McLaren P1, tone of the fastest road cars in the world.
Learn how they did in the the above making-of video. (Hat-tip, Wired).
