A company called Golfstream has designed a simulator that allows users to play 18 holes of golf at any course in the world, and the greens mechanically shift to replicate the consistency of the actual course. If this sounds complicated, you're right. That's why one of the engineers on this project for Golfstream is Brian Childs, who also builds rockets and satellites for NASA's Jet Propulsion Lab. The company bills itself as "future of indoor entertainment," and will be showcasing the simulator through March 6 at the TaylorMade Golf Experience in Las Vegas.
