A Japanese artist's painting transformed by the Sept. 11 terror attacks in 2001 has been displayed at a memorial museum built at ground zero in New York, with the artist hoping his work will help heal the victims and their families.

"Stars of the Forest: Elegy for 9/11," an acrylic painting by New York-based artist Naoto Nakagawa, shows dozens of star-shaped moss against a blue background with white, yellow and orange lights permeating the surface, representing the victims of the 2001 plane attacks on the World Trade Center's twin towers.

"This work is not an expression of anger like (Pablo) Picasso's Guernica. Rather than anger, I have expressed healing," the 77-year-old artist said.
