Abstract: In this invention, a computer-interactive swingable member with a seat thereon is suspended from a swing-support member and swingable in a vertical arc by leg-and-feet muscle power with the feet of an individual sitting on the seat engaged in stirrups positioned in front of the swingable member. The swingable member is horizontally pivotal on an extension from a base member by arm-and-hand muscle power with the hands grasping joystick handlebars. A marker on a computer monitor is computer-interactively engaged with the movement of the seat such that swinging motion of the seat causes the marker to travel selectively up-and-down and side-to-side rotation of the seat causes the marker to travel selectively from-side-to-side on a computer monitor. Resistance to swinging and side-to-side motion can be provided selectively for exercise and the computer can be programmable for selected game and design computer software.
