The Rainbow Mansion sits high on a hill overlooking Silicon Valley. With a roof of Spanish tile and a chandelier in the foyer, this 5,000-square-foot West Coast mini-palace was once home to a man who made his millions selling chips for PC graphics cards and CD-ROM drives. But today, it’s a kind of Silicon Valley commune, a place where the Young Turks of the tech world can live and share their work.
