Aerotrim

The aerotrim (also know as Multi-Axis Trainer) is a device used to cardiovascular workout and balance training in pilots and astronauts. While it was first used as a form of entertainment as an attraction but it later was used as a training tool. The device spins the occupants  inside under 3 rotational axes and they would feel the momentum and blood in their head in feet. In the past astronauts trained like this because the capsule's shape would cause it to spin in all directions but astronauts now use plane like shuttles that are easier to control and so NASA stopped using them. But they are still a staple of space camp and a symbol of astronaut training.

This model uses 215 pieces and holds two occupants and can rotate in 3 axes by turning a crank.
