OK, all but the first picture have changes. I initially got the light, a river or creek, a flat piece of something with holes in it and a plate with some kind of dessert on it. My first impression of the first two pictures was light water, as in nuclear power plants. The second two were vague to me so I started doing google searches and finally tried "perforated plate" and discovered that that too is a component in nuclear power plants. Probably a coincidence. Thanks for checking.
It bears watching. Like I said, it was strange that when you plugged the numbers in separately, that the pictures...changed.
