A billionaire bachelor's playground

What would you do if you suddenly became a billionaire with the means to indulge your every whim, no matter how extreme?

If you're Paul Allen, co-founder of Microsoft, and you liked space travel, Jacques Cousteau, and Jimi Hendrix during your youth, why not go for a personal space rocket, build yourself a submarine, and buy the guitar Jimi used to play "The Star-Spangled Banner" at Woodstock?

Unlike Allen, Bill Gates has been in the public eye for decades and we all know how he spends his billions. But as you'll learn in Lesley Stahl's "60 Minutes" report, Allen has been more reclusive (Lesley compares him to Howard Hughes), pursuing eclectic personal interests and battling cancer since he left Microsoft in 1983.

With the release of his new book, "Idea Man: A Memoir by the Co-founder of Microsoft," Allen allowed "60 Minutes" cameras in to capture what billions have bought for this bachelor, as well as access to his personal home-movie archive. Tonight's television broadcast report on Allen, produced by Shachar Bar-On, and our web-only "60 Minutes Overtime" features are a rare peek into one man's very unique life.
