The most famous artwork in the AROS Aarhus Art Museum in Denmark is probably Boy, 1999, by Ron Mueck. This oversized 500 kg but otherwise very realistic 4.5-meter tall sculpture of a boy squatting. The facial expression of the boy seems to change depending on the vantage point of the spectator – from fear and anger to a more naughty, playful smile when standing between his elbows.
