What's going on around the globe As 5pm nears, 180 artists throughout Melbourne sit by their radios, waiting for the word that will start them on what's billed as '24 hours of artistic madness'. The next evening, at the city's Kingston Arts Centre, they jostle to submit what they've created. Many works are still wet, and some weary artists are adding final touches as they wait. It's the city's 10-year-old Artz Blitz, with artists vying for A$3,000 (about $16,500) worth of prizes and the chance to sell their works in an exhibition that's limited to 180 places. They're allotted to the first to register and pay the A$25 fee. They then wait for the theme to be announce on radio on the Friday evening. This year, it was Power. 'There's this buzzing at 5pm on Friday,' says centre director Adrian Nunes. Delivery time is fun - often with more than a hint of madness. 'We measure and review the art works. If they're not in the guidelines we say we'll show it but it can't be judged. Some people take their works away and saw or knock a bit off.' One of this year's participants was Janet Hulme, a former scenic artist and art director for Disneyland in Tokyo. (She says she wanted to work on Hong Kong's Disneyland, but motherhood intervened.) 'You feel like you're in the 1920s, sitting by the radio,' she says. 'Artz Blitz always inspires me. I send hubby to bed early, I put the easel there and have a cuppa or a glass of wine and mull over what I want to paint.' This year, she was painting against the clock. Although entrants have until 6pm on the Saturday, a friend of Hulme's was getting married that day so she had to be finished by dawn. But the theme didn't inspire her. 'I walked into the backyard, where we have an outside light. And I thought, 'Of course'. It took me two hours. Then I went to bed.' On the Sunday, Hulme and dozens of other artists, friends and family headed down to the two-room gallery to see what the judges had decided. And the winning image? That timeless symbol of inspiration: Hulme's light bulb.
