Thanks, Simon and John W!
Thought it might be of interest to list the pics I used, at least what I know about them:
0:07 - somewhere in British Columbia, Canada (I think).
0:13 - a Shay (geared) locomotive and logging train near North Bend (Washington state) with Mount Si visible, c.1904. How this relates to this thread's topic of 'home', is that back in the day, one of my kin climbed Mount Si when she belonged to a climbing group, and as to the logging, there were many people on both sides of my family who worked in logging going back a long ways.
0:20 - center of video: Potomac Electric Power Co, Benning plant IV. Judging by the cars, I'd say 1920s-30s.
Left/right background: rainforest thousands of miles away on other side of the U.S. Tall smokestacks are an unappealing substitute for tall trees, but I have to admit that electric power is a useful thing.
0:26 - a 1905 painting, "Hawaiian Nights" with mandolin (although a rather small one), by Leon Lippert. An article says mandolins were quite popular in Hawaii during that time period, which I hadn't known. I was suspicious that maybe the painter had painted the wrong instrument (small mandolin instead of uke), but maybe he had it right.
0:32 - center of video: telephone switchboard operator, 1922.
0:37 - left side of video: Port Of Seattle radio operator for ship communications, 1921. I chose this pic because some of my 'home' kin worked in various RF-related jobs. MOHAI says about this pic:
"The Port of Seattle was very busy during the 1920s. The harbor radio station, call letters KPE, was located on Pier 1 at the end of Yesler Way. Ships leaving or entering the harbor radioed their estimated arrival or leaving times and other messages to KPE. This helped the port control ship traffic. This photo shows a wireless radio operator at the Port of Seattle."
The right side of that part of the video shows modern ship traffic, to sort of tie it in with the companion pic of the 1921 radio guy.
0:50 - center of video: "Peasant Girl With Sheep", c.1895 painting by Julien Dupre.
Left/right background: Mt. Rainier (my picture is reversed), one of that region's active volcanos (Mt. Rainier is a ways north of its more-famously-active cousin Mt. St. Helens). Haven't seen shepherds there though.
0:55 - a modern ship. By the looks of the terrain I'd say probably somewhere in either British Columbia (Canada) or Puget Sound (Washington state). I used to think such ships were oil tankers but I could be wrong.
1:02 - a lake, possibly in Canada, not sure. (Some of my internet free clip-art sources aren't very informative as to where pictures were taken.)
1:07 - a Merganthaler linotype machine in 1906 in Seattle, setting type for the Pacific Tribune which was a Swedish-language weekly newspaper. There were many immigrants there from Scandinavian countries, so a foreign-language newspaper was not unusual at the time. The linotype machine looks cool from a gadget-freak point of view, but I've heard that some linotype machines were also risky if you worked with them long enough (asbestos and lead exposure etc).
1:19 - Seattle High School Mandolin Club, 1903.
1:31 - center of video: ladies with lute or mandolin or something, Eduardo Galli (c.1854-1920).
Left/right sides of video: I added 'paneling' on both sides - I made the right side slightly animated (it slides a little) in an effort to create an effect of walking into the room and seeing more of what's there.
