Waitati designer Paul Cardno's kinetic sculpture The Corner Dairy Number One has been enchanting young and old since it was unveiled in the mall on April 13.
"It's had a fabulous response. I'm really, really pleased. It's been fantastic," Mr Cardno said this week.
"I really built it for me and it's interesting why other people are interested in it. But it's great that it gives people so much pleasure," he said.
"I wanted it to be launched in a public place, so that people who don't usually go to art galleries would get to see it."
The $15,000 kinetic sculpture juggles 14 balls inside a complex bird's nest of wiring, with the aid of infrared sensors, solenoids, micro-controllers and servo motors.
"It's self-managing. If no balls come out after three minutes, it sends me a text message," Mr Cardno said.
It took the Waitati designer and programmer four years and more than 160m of wiring to build. He is an established painter and sculptor and has a master's degree in physics.
"It brings all those worlds together."
The Corner Dairy Number One can be seen in the mall until May 20.
