Controlling light so subtly several small beams are directed to swirl around each other and never spreading apart like a gaussian beam.
This is a big deal for communications, say you have a beam that would be say one cm in diameter, and a thousand Km down the road the beam is 1 cm in diameter still.
Awesome development!
