you did mentioned todays we can get many LEDs for the price of an motor , here a simple motor costs about $1 and for this price you ...
It was never the price. I mentioned the price as a reason that it might have been an idea in the olden days.

Now, there is the one for the spokes, that one makes sense as a novelty item. I have real trouble seeing the clock (which is, at best, difficult to read) as an attractive marketable product, but knowing kids, I can see the spoke thingy having appeal.

Anyhow to make one thing clear I have no problem with the rotary clock, my problem is that since we rarely see "product displays" here and, if "product displays" were to be a feature, there would be, at least hundereds, that would show marketable creativity. Thus why on earth make a big fuzz on something as unattractive as a swinging arm with LEDs.
