Blue Green Light Bulb Kaleidoscope by Japanese artist Yukinobu Kitamura
A bright idea for a kaleidoscope!!
The object chamber, located under the screw thread contains small bits and pieces of colorful glass and dichroic film which are further enhanced by the internal battery operated LED light. Unscrew the cap to deactivate the LED light and save battery power while not viewing the kaleidoscope.
Blue Green Light Bulb Kaleidoscope has a 3 mirror system with a full field of manadala imagery.
