The Calling by Haroon Mirza (2013) —
The $50,000 prize rewards artist's whose work is in some way reminiscent of Calder's. Last year's recipient, British artist Haroon Mirza, was celebrated at the launch last week.

Untitled by Tara Donovan (2015) —
"His focus on the potential of materials and how their physical properties allowed him to work with varying scales and exploit the kinetic potential of modular forms is a testament to his playful approach to working, which relies on experimentation and dialogue. This approach is one I have attempted to emulate in my own practice," said inaugural prize winner. (She created the sculpture seen here out of Slinkys.)

IOHEfU by Darren Bader —
Similarly, Darren Bader said of Calder's influence: "Being an integral part of so-called Modern art, he's had incalculable influence on how I think. Like so many of the Modernists we continue to revere, he asked good questions."

Cumulus Filaments by Tomás Saraceno (2016) —
"We share the same passion about the universe, in its cosmic plenum, said Tomás Saraceno, a trained architect who makes complex installations out of rope. "Inasmuch as he found his balance and movement in fixed mobiles, I have been experimenting with movement by creating flying sculptures that can revolve around the planet."

Flux by Zilvinas Kempinas (2009) —
"Throughout his long and very productive career, Calder managed to capture the character of his times, to the point that it is hard to imagine this era without his work," said 2007 winner Zilvinas Kempinas. "However his iconic sculptures still look surprisingly fresh and robust today, doing their thing, moving with authentic grace all the way into 21st Century."
