The teleidoscope is a kaleidoscope with a telescopic eye. Rather than using bits of colored glass, the teleidoscope projects the light rays down into the tube and mirrors create multiple reflections. Each reflection forms one section of the pattern.
For the teleidoscopic effect move the lamp, not the teleidoscope. Or, move objects in front of the lamp such as a printed page. Set lamp on LOW. CAUTION: Do NOT let the light shine directly into the TV camera.
