A hollow sphere formed from a plurality of contra-spiralling members extending through 360 DEG from one end of an axis to the other to form a geodesic frame. Latitudinally extending spaced and parallel reinforcing members may be used to brace the frame. An axle may extend along the axis and may include an elastic motor for the embodiment when used as a toy, a pedal and gear assembly when used as a recreational device and a source of a power when used as a mobile powered device.
