Abstract: The present invention provides for a kaleidoscope which creates a newest ever pattern, and a pattern generating apparatus and a pattern generating method utilizing such a kaleidoscope. A tip-cut polygonal cone cylinder 1 has both ends 1a and 1b open and peripheral surfaces formed by plate members 1A whose wall surfaces are mirror surfaces. A film printing an object is disposed at an opening of a leading end which serves as a cut tip surface 1F having a small cross sectional area, the film is irradiated from behind, and the object is viewed through an opening of a rear end of the tip-cut polygonal cone cylinder. The cut tip surface 1F is an inclined surface which is inclined with respect to the longitudinal direction of the tip-cut polygonal cone cylinder 1.
