Shape-shifting sculptures explore the fourth dimension

The Art of Movement is a monthly show that highlights the most significant innovations in science and technology that are helping shape our modern world.

(CNN)For most sculptors, a stable work of art is something of a priority. Not so for kinetic artist and designer Ralfonso.

The Swiss sculptor, whose work can be found in countries all over the world, gives his creations the power to change shape as they move in the wind. Each design is unique and relies upon "mechanics and a bit of engineering," Ralfonso says, to ensure "the elements don't hit each other as wind speeds increase."

His futuristic sculptures may be created from stainless-steel, fiberglass and Kevlar laminates, but the inspiration behind them is rather more bucolic.
    "I am really inspired by nature," Ralfonso explains. "As things move in nature -- whether it's a tree or tall grass, or whether it's a leaf that falls and the motion of it ... I'm fascinated by the best of all designers: Mother Nature."
    Transience is a key theme in his oeuvre. "It is so much more interesting to have art that changes over time," he argues. "You're kind of exploring the fourth dimension -- the three dimensions of a sculpture, plus the fourth, which is time and change over time."
    This manifests itself most subtly in the ever-changing configuration of his sculptures. In his work "Union," located in Orlando, Florida, an array of 3,000 LED bulbs scatters light off the turning elements, transforming the way we see the artwork once night falls.
    The kinetic artist has big plans for the future. Ralfonso wants to build more wind sculptures, and on an even larger scale -- so long as Mother Nature provides the wind to make his art move.
