This was no where near any of the places I spent in Kazakhstan, but on my next trip I really want to go to Pentagram Park. I'm guessing the reason it is "upside down" is because the people building it were thinking of their red star from the vantage point of Russia, which is North of the site.
Actually, the whole thing works as a metaphor for the Soviet Union: out of date, currently abandoned, pretending to be about all its nationalities but really centered on Russia, and appearing like a symbol of the devil to those inclined to see such things.
