ABSTRACT:
A housing contains a rotating platform mounted on a shaft which is driven by a motor which can be operated by a battery, flowers plants and bells are mounted on the platform and a butterfly is mounted through a slot in a collar of the housing surrounding the platform, the wire supporting the butterfly is caused to vibrate by a cog wheel mounted on the shaft which causes cogs to press against the wire supporting the butterfly, another cog wheel mounted on the shaft causes a hammer mounted within the housing to gently hit a bell depending from a support within the housing, causing gentle bell like sounds while the butterfly moves around undulatingly as the platform rotates.
