"Sometimes it's nice to have a bit of humor on serious subjects," said McCartney, whose island will be open through July 29, in a statement.

Those who take a trip to the online idyll will be able to scoop real-world prizes, too. A competition will run until July 19, for which visitors can submit a new PETA slogan, based around its tag line, "I'd rather go naked than wear fur." Prizes will include two tickets to McCartney's spring 2008 show in Paris, one of the designer's Appaloosa bags and her entire Care skin care line.

PETRA'S CAUSE: On Monday, model Petra Nemcova feted a partnership between her Happy Hearts Fund and NutraCea, a leader in nutrient research and supplement development. The Cooper-Hewitt Museum exhibit "Design for the Other 90%," featuring objects designed to aid the impoverished global population, was an elegant backdrop for the event. "It's amazing the support I've gotten from the arts and entertainment communities," Nemcova said. Guests included designers Tiffany Koury and Loris Diran and Russell Simmons. Through the partnership, Nemcova plans to make NutraCea products available to families still suffering from the Indonesian tsunami she survived in 2004, and to expand the program from there. NutraCea president and chief executive officer Brad Edson summed up their future plans by saying, "There are a billion starving people in the world. When they're all fed, then we'll stop."
