Too bad none of the pictures includes something to give an idea of scale. It's pretty much impossible to get a good idea of how big these things are. I have no idea why the first poster thinks the use of "panopticon" might be pejorative. Perhaps he doesn't understand what the word means. Abusive comment hidden. (Show it anyway.)
