WEST LAFAYETTE, Ind. (AP) - A new mini-film is shedding light on how a high-tech method developed at Purdue University can make worn historical objects look new again.

Filmmakers from a branch of the American Institute of Physics recently produced a 90-second mini-documentary on Purdue's "virtual restoration" process.

The film shows how a Purdue team can make deteriorated artifacts look new by using computer software to project millions of tiny lights onto them to restore their missing colors.

The method gives the illusion of restoration without physically altering historical objects.

The Purdue team demonstrated their process earlier this year at the Eiteljorg Museum of Native American Art and at the Indianapolis Museum of Art.
