The Kiwi who won a prestigious art award with a photograph of urine samples last night revealed the bizarre secret of his success.
Wellington-based fine arts student Elton Irvine, right, was chosen from 200 entries as the $5000 supreme winner of the Arts Gold awards in Alexandra, Central Otago, on Friday night.
Judges described his shot of urine-filled test tubes, pictured, as "unusually beautiful".
Irvine, 39, said he collected his own urine for six weeks to experiment for the pictures after dreaming up the idea in a pub.
