Simulations in real life.

In Las Vegas at Circus Circus, they have this simulation in the Arcade called CyberCoster. It allows you (for $5 per person) to "design" a roller coaster ride from a series of pre-set selections (example, loops, dips, etc). Then you sit inside the simulation car (it looks like a smaller version of Star Tours at Disneyland) and they close you inside and run your simulation. There's only room for about 2 people. Kids under a certian height and age are not allowed. It was really interesting to see a real life example of a simulations.
