Scott Jones, CEO of search engine ChaCha, has built a high-tech wonderland of a mansion in central Indiana to rival any abode in Silicon Valley. The 27,000 sq. ft. English country manor, selected by HGTV as the No. 1 home in America, melds old-world charm with a hardcore nerd's wet dreams. Amenities include the obligatory, and thoroughly geeky, automated lighting, air conditioning, and media systems controlled by touchscreen and a workstation sporting eight large LCDs (one of twenty-six computers in the home). Jones's playthings, however, don't stop with the typical high technology.
