The word teleidoscope is a hybrid of the words "telescope" and "kaleidoscope" — a kaleidoscope that turns whatever you point it toward into a radial pattern. Is this cool, or what? I had no idea such a thing existed, though after the fact it makes perfect sense. [slow brain icon] It tells more about it in the link below; and, I recommend that anyone with an interest in art try the home page--there's also a free web page translator available, though I did not try it and thus can't say how accurate it is or isn't. Artlex Note--there are a couple of ads on the page.

i collect kaleidoscopes, and also have several teleidoscopes, and a karascope.
the karascope is tube similar to standard kaleidoscopes, and it has bits of glass at one end. (and internal mirrors, too.)
the bits of glass in a karascope are clear, flat disks of various sizes. each one is polarized. thus, each allows only a certain limited percentage of light to travel through it.
depending on the light sourse--be it natural(white) light, or halogen, incandesent, or floresent, the disks will filter out certain frequencies, and appear to change color.
it's a very interesting effect. i have halogen, florescent, and incandesent lights in use in my home, as well as a 'black lights'. by using different light sources (or a mix!) for viewing, the karascope changes quite radically in how 'colorful' it is.
some artificial light sources are quite white (that is, they offer almost a full spectrum of color) other artificial light sources are warm (they have a large percentage of Red/orange /yellow light (but almost no green/blue/violet.) and some are 'cool' (mostly blues/indigo/violet).
on my sunniest window, i have 3 different prisms--and often have rainbows arcing across the room. (i keep a large (10 inch square) flat (plastic) fresnel lens handy, too, for fun.
i have also build kaleidoscopes from kits, and i have another set of mirrors to build another kaleidoscope--not a kit, just the mirrors.
i am enamored by light, and color (as an aspect of light).

Jackie, thank you for this one, definitely a candidate, and very new at that. Many hits are lower case and so if you have the wherewithal to find out without going to too much trouble, can we assume it merely a coinage and not a registered trade mark
Better yet can you cite an online official listing of registered terms, or even better, of once-registered but now in public domain and thus fair game without the cap.

Neat, Helen; I was hoping you'd see this thread! In Dick Francis' book Reflex, the main character talks about learning to mix colors with light, as opposed to paint. It sounds like you've had some experience with that.
Edit--good gracious, Dale--all I know is what was in the link, sorry! Sounded like a portmanteau word to me.

Well, that is interesting OT - you've taught me a new word. I've just learned that the thing I have is not a kaleidoscope, like I thought, but, a karascope like you have.
Hubby got it for me years ago and I always loved how the display inside was affected by the different type of light I exposed it to.

right now, (early afternoon, on a cloudy day) part of my white ceiling are a darker grey than my grey walls. at every joint where the wall meets the ceiling, its quite clear that the walls are darker, but the diffused soft light leaves the ceiling, not sparkling, but a gradient grey (whiter closer to the windows, darker and darker, as you move further away)
--and while it is cloudy, its still bright--so the grey wall that is opposite the bright yellow wall looks moss green instead of grey. (the grey is a bluish grey)
i thought a good deal about the colors for my walls (and ceilings) my main (living/dining/computer room) ceiling color is an artic (blue) white. -(the bedroom ceiling are blue--pale sky blue--but most definatelly blue!)
In the daylight, its obvious the yellow (computer room) is a pure tone--a true yellow. but at night, it looks ever so slightly yellow green- the relected light of the living/dining room overwhelms the yellow--especially when only the low watt energy saving florescent lights are on--with the cool blue light they emit.
but in the daylight (or with the (yellow) incandesent lights on, the yellow can over power the grey,(at least in one corner) and make it look like a grey/green (pale moss/sage in tone!)
i love that i change the colors of the walls simple by turning on (or off) key light fixtures.
i am tone deaf (as much as enjoy music, i realize this) but i have something like perfect pitch when it comes to being able to 'see colors'.
