I’ve occasionally searched for this on Ebay over several years, and this item’s never come up, but I’ve never been able to forget it, even though I only glimpsed it for a few seconds in the late '70’s, when I was a kid.
The table clock in question was stunning, more graphic art object than utilitarian object: smooth chrome housing, with an unusual tubular shape (more detail on that below). The eye-catching aspect, though, was the clock face, made of laser-etched? optic material yielding a brilliantly backlit, intensely hued rainbow of ever-changing colors. A minimalist large circle (the second hand), composed of the same material, generated its own explosion of color as it slowly revolved and interacted with the background colors – as overlapping bits of glass will generate new colors in a kaleidoscope. I don’t recall any numbers on the face; time might have been indicated by minimalist hands (in black, I think) and one, four, or even no hour place markings. And the face was brightly lit when viewed from straight ahead – so much so that it seemed that in a dark room, the clock might well cast its colors on the opposite wall.
As for the clock’s shape, it was like that of a…[one of those big air tubes on the decks of ships; dunno what they’re called] or an elbow pipe section. The chrome tube rose up from the table surface and bent 90 degrees to display the face, which was recessed about an inch or two from the outer lip of chrome (no doubt to protect the delicate materials in the face). The upshot of this design is that this was definitely a table clock best appreciated from a short distance; you probably couldn’t see enough of the face to read the time if you glanced at from an oblique angle.
The clock was approximately 7" tall with a tube and face diameter of about 5". It had a price tag of $400, and this was around 1978 (possibly 1976-79). It was certainly worth every penny, so evident was its craftsmanship, ingenious design, and beauty. [Then again, maybe I’m just mesmerized by bright, shiny, colorful objects. 
] The store was an upscale designer-furnishings boutique, and it was, I think, either in the Omni International Mall in Miami, or possibly the Peachtree complex in Atlanta.
Does anybody else recall seeing this clock, and recall any concrete details, esp. info on the designer or manufacturer, the year, or the materials used?
