Regarding your inquiry about motion lamps, that is an accepted
term for them. However in many patent applications they were
more often described as "animated decorative lamps."

> Greetings!
> I'm seeking information on American antique lamps from the 20'-30's(?).
>  I've been unable to determine the correct name for these lamps.
> Description:  12-16 in. ht.  Approx. 6-8 in. diameter (cylindrical).
>
> These are motion lamps - I believe operated by the heat generated by the
> bulb.
> The moving cylinder inside the lamp contains a graphic - usually Currier &
> Ives style.  As the cylinder rotates, the moire' pattern gives the
illusion
> of motion within the graphic.  For example: waterfall - forest fire - or
old
> time locomotive.
> Can anyone tell me the formal name for these lamps, or where to find
> information about them?
> Thanks to all,
