Kaleidoscope

I present to you today something unusual that you can enjoy for a long time. Some of us may remember it as a toy, but when it's done with precision, it is a marvel to behold, as you can see from the image presented here.  A kaleidoscope is an optical instrument with two or more reflecting surfaces or mirrors tilted to each other at an angle, so that one or more parts of objects on one end of these mirrors are shown as a regular symmetrical pattern when viewed from the other end, due to repeated reflection. The term "kaleidoscope" was coined by its Scottish inventor David Brewster, and the first patent was granted on July 10, 1817. He experimented with glass, mirrors and other gadgets to create his finished product, which was perfected over the past 200 years. Enjoy what you see, as the image changes constantly. Make sure to put the image on Full Screen.
