In 2004, truck driver Joe Macken began with a tiny Rockefeller Center building; more than two decades later, his vast handmade New York model entered a city museum

In the spring of 2004, Joe Macken went into his basement in Clifton Park, New York, and started a project he could not yet imagine. He wanted to see whether he could make something from balsa wood. Two decades later, his basement project has grown into a vast collection of miniature buildings in a scale model of New York City. It's now a public attraction inside a Manhattan museum. Macken began by whittling down a small version of the GE Building at 30 Rockefeller Plaza, according to CBS News. He enjoyed making it so much that he started another building the next day. He kept going after that.
