Zappos CEO Tony Hsieh wants to transform Sin City's downtown into a thriving, culture-rich community with his $350 million Downtown Project. Entrepreneurs are the lynchpin of the five-year plan, which began in 2011 and includes an emphasis on the arts, education and urban development. Hsieh's personal fortune is funding much of the project with $50 million being invested in tech startups and another $50 million in small businesses. Education initiatives are being allotted $50 million, while the remaining $200 million is being spent on real estate. In this final part of our series, we look at the city in the process of reinvention.
