Carrie Underwood used the huge skirt of her gray dress as a digital projector during her Grammy Awards performance.
As she sang "Blown Away" and " Two Black Cadillacs" various images flashed on her dress.
"They can do a lot of amazing things with projectors these days," she said backstage, holding her trophy for best country solo performance. "We had a dress especially made. I said I should take that home and we can watch movies on it.”
Underwood said she had to stand in a specific spot on the Staples Center stage to make it work.
"It took a lot of precision," she said.
