Videotaping a rainbow over Machu Picchu was a peak experience during Patty Mooney's recent trip to Peru to collect stock footage for New & Unique Videos, a stock-footage library that grew out of her round-the-world mountain-biking aned videography trip in 1993 and 1994. Another Mooney venture is Crystal Pyramid Productions, a video-production company that has worked on projects for "The Oprah Winfrey Show," shot Shasta commercials in Tijuana and captures the X Games for HBO/ ESPN. "Everybody here has the same philosphy. Enjoy your work," says Mooney.  "With that attitude, you make it fun for the client."
