ABSTRACT:
Embodiments disclosed herein may include a toy method and system configured to be displaced for generally long distances by a small force. The disc-like or ring-like device may utilize wind-related vortex forces to remain generally upright and moving for long distances. Furthermore, the system may comprise an aperture, and may have a aerodynamic configuration to achieve the movement and/or provide for use as a flying disc. The ring-like device may be configured as an annular wing having a symmetrical airfoil configuration and as such may be used both as a wind-driven rolling toy and as a hand-tossed flying ring.
