Evento's Buzzball is is a giant ball with a seat in it that's being hailed as a one-person roller coaster.
At the heart of the Buzzball is a dual motor configuration, enabling the pilot to control the motion and direction of travel via left and right control triggers, which provides power to the driving wheels.
The amount of power applied to each wheel will determine the direction the Buzzball moves.
Once the Buzzball is in motion the pod maintains an upright position until the pilot turns, causing the pod to rotate inside the ball against the direction of travel, which applies a braking force and the pod to lock with the ball. This causes the pod to rotate with the ball until the weight of the pilot and pod overcomes the inertia forces and causes the Buzzball to change direction.
This is when the fun starts, as the speed will affect the degree of rotation of the pilot and pod from a partial barrel roll to complete and multiple rotations!
Okay, so let me give it to you in layman's terms: You get in this giant freaking ball, pull some levers and shit, and the next thing you know you're puking, and, oh God, drowning in a creek. Now that's what I call a good time.

Thanks Ray, one time I rode a coaster and puked on the lady next to me.
