This is a Japanese traditional toy, Kendama in Cycle. Playing the toy is basically to throw the ball and receive it by the wooden body. But sorry the Kendama lacks string ting ball with body since I can't make physically correct rope between them.
Other animation and images are Blender CGI: Kendama physics.
Thanks for the model, ill exactly make a string and attach it for an interactive/game movie im making (more like testing).
