Gerald Holtom's Flags

Origin
Gerald Herbert Holtom (January 20, 1914-September 18, 1985) was a British professional designer and artist. In 1958 he designed the logo of the British Campaign for Nuclear Disarmament (CND), which became an international peace symbol.

Effect
When the user makes the semaphore for "N" and "D" with the flags, all nuclear weapons in a 10 mile radius will become disarmed. The effect is slow and usually takes 30 minutes.
