CBS : Frank Kovac, of Monico, Wisconsin, has built the world’s largest rolling, mechanical, globe planetarium—in his backyard. When younger, Kovac had dreams of becoming an astrophysicist, but instead ended up working in a paper mill. Nevertheless, he has spent the past 15 years building the Kovac Planetarium , hand-painting some 5000 stars on its ceiling and installing an electric, variable-speed motor controller to spin the globe itself. Now complete, it is open to the public seven days a week, with an admission charge of $12.
