Duo

This kaleidoscope has a dual function viewer: you can see the effects produced inside it by the coloured glass and the treatment carved into the mirror, and on the other hand you can place a photograph or an image underneath it to see it in kaleidoscope effect. But the most addictive thing we have tried so far is to place underneath a phone playing videos of fractals or geometric shapes in movement. They are very easy to find on YouTube, and seen through this kaleidoscope they are spectacular. In the attached video you can see a small sample, but nothing like seeing it in person!
