Award winning! Torus Revolution received the 1st place People's Choice Award at the International Kaleidoscope Expo in St. Louis MO in May 2022! This unique design measuring 15" long by 2" diameter features a liquid filled static cell, 8 piece mirror assembly with dichroic mirror and free rolling glass spheres. All these factors contribute to the amazing, immersive kaleidoscopic experience that you'll discover inside. The image changes dramatically as the entire scope is rotated. Light entering the two windows floods through the dichroic mirrors creating mesmerizing interplay with light and color. The free rolling spheres can be controlled with tilting and rotating. It has been described as my best work thus far. Color on exterior will be similar to the photo of the exterior. These will be made to order, so if you have a particular exterior color idea, just make a note in the order.
