Fish swim around coral formations in an artificial reef at Pemuteran Bay in Bali, Indonesia, on January 18, 2004.

An experimental project by scientist Thomas Goreau and the late architect Wolf Hilbertz to electrically stimulate the growth of destroyed corals has been a success, experts say.

The corals in Pemuteran now teem with clownfish, damselfish, and other colorful tropical animals.

Kadek Darma, a Balinese, told the Associated Press that the corals benefit to the local economy were obvious.

"They attract the tourists, and more tourists means more jobs," he said. " I hope we can all keep maintaining the reefs for our great-great grandchildren."
