Wyatt, , published November 1817, →OCLC, page 321:

     The Kaleidoscope (from καλος beautiful, ειδος a form, and σκοπεω to see) is an instrument for creating and exhibiting an infinite variety of beautiful forms, and is constructed in such a manner as either to please the eye, by an ever-varying succession of splendid tints and symmetrical forms, or to enable the observer to render permanent such as may appear most appropriate for any of the numerous branches of the ornamental arts.

     The mind of Petrarch was like a kaleidoscope. At every turn it presents us with new forms, always fantastic, occasionally beautiful; and we can scarcely believe that all these varieties have been produced by the same worthless fragments of glass.

     Detractors saw the kaleidoscope as an expression of a mass consumer culture that could be all too easily distracted by the shiniest new baubles and sensations. […] The revolution that Steve Jobs triggered in 2007 with the launch of the iPhone means that most of us now have a modern day kaleidoscope in our pockets.

2. (figuratively) A constantly changing series of colours or other things.

     Lady Etheringhame being now a constitutionalist, dined rather early: and Emily, her head like a kaleidescope, full of colours, with not a little disdain, put on the blue silk she had thought bleu céleste, at least in the country.

     The rail journey from The Hook [i.e., the Hook of Holland] to Basle is a scenic kaleidoscope, ranging from the flat terrain of the Netherlands to the high ranges of the Black Forest, from the straight Dutch waterways to the sinuous Rhine gorge, from the ocean-going shipping of canals to the busy inland traffic of the Rhine and from peaceful farmland to thriving centres of commerce.

     The chip smells like nothing, but tastes like a smörgåsbord that's both confusing and arousing, like Steve Buscemi. Flecks of spring green – the kind generated from radioactive waste – coat the unwieldy triangles. The seasoning is a kaleidoscope of Day-Glo dust particles that perishes under saliva and tongue.
