This is a brass teleidoscope by Roy Cohen. This scope has a 3-mirror system and at the top of the set of mirrors there is a fish eye lens. The lens reflects whatever the viewer looks at through the scope. The familiar environment is then broken into tiny particles that are multiplied and reflected into infinity. This scope is signed and dated by the artist, it measures 5"L x 7/8" in diameter and it comes with the small metal stand pictured.
