Dragon, fly away

A dragon fly on a fig branch.

A dragonfly has extraordinary visual capabilities. Two large compound eyes each contain up to 30,000 facets. Each facet “faces in a slightly different direction and resolves a separate image,” enabling it to see in almost every direction simultaneously (from Dragonflies by Cynthia Berger, page 22).

As aerodynamic wonders, dragonflies have long intrigued the U.S. military and NASA. Wing design allows these aerial acrobats to launch vertically, hover motionless for up to a minute, make zigzag maneuvers and stop on a dime.

Are dragonflies mere mutants or masterpieces of divine design? Think about it.
