Never seen anything similar. Well... When I was maybe about 10 or 12 we 
went to my mother's village for the summer. No water at the houses (they 
had to pick it from a fountain at the plaza), and no electricity. Ok, 
they had electricity, one bulb in the main room, maybe another upstairs. 
There was no meter, they were charged by the number of bulbs. No sockets 
at all. No fridge. No gas cooker, but my mother brought one. Horses were 
actually used. We did #1 and #2 at the pile of manure downstairs at the 
stable. This would be about 1970. All this was amazing to me, I grew on 
a city.

My father brought his 8 mm cine projector (no super 8), and connected it 
to the bulb holder. I think they were amazed, I don't recall. My father 
had shot some scenes of village life, and they saw themselves on the screen.

Oh, and we travelled on a Seat 600.
