another toy that has grown up - it is all done with mirrors
What is the difference between a kaleidoscope & a teleidoscope? It is in the end - a kaleidoscope has an object box that is filled with loose bits of glass, gemstones, flowers, whatever, that may be dry or floating in oil. Teleidoscopes give you the outside world - transformed. A lens captures those flowers, faces, traffic, bright lights and creates an infinite & everchanging kaleidoscopic experience.
