A new wave of moving digital art is emerging - and Apple technologies are involved.

A new permanent exhibit at the University of California's Berkeley Art Museum has been created by artist Naomie Kremer. Digital artwork "Rudimentary Moves" has music and sound effects and runs in a four-minute loop.

A report on Apple's site explains the piece: "At first, the abstract painting dominating the museum wall appears as fixed as dry ink on paper.

"Then the paint moves. Brush strokes shimmer like wind chimes, and the whole painting trembles as if it's experiencing an earthquake. After every stroke in the painting collapses in a heap and disappears, the painting reassembles itself, stroke by stroke, in an animated sequence."

The artist explained how using digital processes unleashed fresh creativity. "What I like about working digitally is that it lets me have other kinds of ideas than in painting," she said.

Kremer made the piece using a dual 2Ghz processor G5 Power Mac, Photoshop and Motion 2.

She believes digital processes to be as valid an art form as any other, saying: "Picasso used to do sculpture, ceramics and printmaking; I think if he were alive today he'd be doing things in digital media."
