I guess my mind is slipping some. I've been looking through it holding it verticle..thats the way I look at things. The image in the periscope was correct, the way it should be with top on top and bottom on bottom. I went to look around a corner expecting the image to now be rolled over...the side of the image to be on bottom and the top of the image to be on the side...
Nope! to my momentary amazement the image was still correctly oriented. Should have known better but you can forget what you learned in college physics class in 40 years or so.
Interesting novelty I guess.
