A 16-year-old looking to boost his art school application took a bow Thursday for being the one behind the grand piano that mysteriously showed up on a sandbar in Miami's Biscayne Bay.

Nicholas Harrington said he wanted to leave his artistic mark on Miami's seascape as the artist Christo did in the early 1980s when he draped 11 small islands in Biscayne Bay with hot pink fabric. And if it helped the high school junior get into Manhattan's Cooper Union college, that would be OK too.
