Koji Yamami is behind some of the coolest kaleidoscopes we have seen. The Venus X Kaleidoscope is also worth a look. Its body is made from iridescent pastel pink stained glass and small squares of dichoric glass. It has a rotating fluid filled glass object chamber on top with highly reflective dichroic glass pieces and strips.
Inside, Venus X has a single tapered mirror system made with both mirror and dichroic glass. There are two eye holes at the base of the kaleidoscope to offer a 3D experience. This scope measures 8-3/4″ tall by 3-3/4″ wide at the base.
