1. A flying disc comprising:
a disc body comprising (i) a central body portion forming an upper surface of said disc body, and (ii) an outer periphery surrounding said central body portion; and a signal-generator positioned along said disc body, said signal-generator being capable of (1) generating a first signal in response to said disc body rotating in a first direction, said first direction being substantially perpendicular to a dissecting axis extending through said central body portion of said disc body, said first signal being a first color, and (2) generating a second signal in response to said disc body rotating in a second direction opposite said first direction, said second signal being a second color that is different from said first color, said signal-generator comprising:
(i) a first component that detects rotation of said disc body in said first direction or said second direction,(ii) a second component that detects direction of rotation of said disc body in either said first direction or said second direction,(iii) a signaling device providing said first and second signals, and(iv) circuitry that connects said first component, said second component, and said signaling device to one another. |
