Indra's Net

Richard and Judith Lang used a ghost net to create their art exhibit, Indra's Net. The net represents how we're all interconnected. The promises on the net – like the jewels on Indra's Net in Hindu legend – hold our wishes, dreams and visions for a healthy ocean habitat for all marine life.

The Ghost Net Monster

Sperm whales dive to depths of 10,000 feet to feed. Sometimes, what seems like food isn't.

never-ending cycle

When the net is freed of fish and debris, it rises again to the surface and repeats the cycle.

"This thing is rising and falling in the ocean, silently moving and capturing anything and everything."
