Various kaleidoscopic devices are provided which utilize removable and replaceable design inserts. The design inserts may be formed from a wide variety of artistic materials and may either be manufactured or prepared by the individual user. The use of these removable and replaceable design inserts greatly increases the viewing flexibility for the user by allowing a large number of designs to be viewed using a single kaleidoscope.
