"Anticrepuscular Lasers"

Jonathan Holt pictured this laser display by Yvette Mattern at New Haven, Connecticut.

The laser beams are parallel, just like the rays and shadows cast by clouds. The top image looks away from the lasers and the rays appear to converge - like anticrepuscular rays - somewhere several miles away.

The beams really are parallel.

They nicely demonstrate the characteristics and appearance of sun rays and shadows.
