Artspace gallery in Auckland has all the usual display walls but that doesn't seem to be enough for them. For the last few years they've also been commissioning works for their stairwell. Two artists have won the elaborately titled Chartwell Stairwell Commission, Aucklander Daphne Simons and Whanganui's Julian Priest. Julian's work will turn the stairwell into a giant musical instrument, played by the feet of visitors to the gallery. Justin Gregory went to do some stairway dancing.
