Structure of crystalline ball with rotary type
 The present invention relates to a structure of crystalline ball with rotary type drive. The drive is coupled to and rotates an eccentric shaft. The shaft is coupled to, a sliding block mounted in a groove frame for vertical movement therein. The eccentric shaft and sliding block are connected to the output shaft and an engagement element such that the sliding block can be driven by the eccentric shaft. A swing sick extended to the outside of the wood base rotates and moves up and down to produce a plurality of variations of dynamic phenomena.
