A kaleidoscope comprises of members including a convex lens, a lens seat, a view lens, an inner bush cylinder, etc. mounted together inside a shell body of the kaleidoscope composed by a front cylinder body and a rear cylinder body; observing forwards from the view window of the rear cylinder body, the figured pattern mirrored on the surface of every plane facet on the convex lens from the surface of the view lens can be seen and displayed in the forms of a multiplicity of figured patterns; optionally, rotating the front cylinder body can control every surface of the plane facets to rotate axially around the axle center on the convex lens, and rotating the rear cylinder body can control the figured pattern inside every plane facet to spin synchronously so as to provide a kaleidoscope with specially interesting effect.
