SOLUTION: A spring 205 and a fall-off preventive piece 213 are provided between mirrors 203a and 203b of the kaleidoscope 201, and one or a plurality of transparent balls 211 or the like are inserted in the space between two sheets of mirrors 203. The size of the space is changed with a spring 205 and admiration is made from the arbitrary direction. A concave mirror may be put on the opposite side of the side peeped into although not shown in the drawing, or an image passed through the kaleidoscope 201 may be projected on the concave mirror.
