In this context, we will take a closer look at the calming and hypnotic effects of kaleidoscope videos.
Just think of the effect of color therapy. The predictable moving patterns of mandalas have a particularly soothing effect on the brain, and especially when the patterns have warm colors, they can even arouse emotions. The visual results are so-called “fractals,” or infinite symmetrical repetitions of patterns. Multiple reflections by two or more reflective surfaces have been known since ancient times and were already described by Giambattista Della Porta in 1589. Yet Brewster’s invention is not the only one of its kind and certainly not the first. The name Kaleidoscope is derived from the Ancient Greek words καλός (kalos), “beautiful, beauty,” εἶδος (eidos), “that which is seen: form, shape” and σκοπέω (skopeō), “to view, examine,” hence “observation of beautiful forms.” The name was first published in the patent granted on July 10, 1817. 4136 was named “for a new Optical Instrument called ‘The Kaleidoscope’ for exhibiting and creating beautiful Forms and Patterns of great use in all the ornamental Arts.” Etymology For this reason, he decided to apply for a patent for his invention. In this way, surrounding objects were clearly displayed in the reflected pattern.īrewster expected his instrument to become of great value, not only for entertainment purposes but also for decorative arts. The final step, considered by Brewster to be the decisive one, was to place the reflective panes in a drawtube with a hollow lens.
He developed a version in which some objects and pieces of glass could move when the tube was rotated. The display multiplied toward the ends of the glass plates”.īrewster used pieces of colored glass and other irregular objects in his experiments. He noticed a circular arrangement of images from a candle around a center point. In 1814, Sir David Brewster conducted experiments on light polarization by successive reflections between glass plates. Sir David Brewster: inventor of the kaleidoscope The rotation of the tube causes the movement of the materials and project an ever-changing image under the influence of the incident light at the other end of the tube. The tube contains mirrors and a cell at one end containing loose, colored pieces of glass or other transparent materials that reflect in the pattern view. When this object is set in motion, a repeated reflection is observable as a regular symmetrical pattern when viewed from the other end.
