Yes, that is what you think it is.
We came across it almost by accident. There was a very small warning, that we missed, about the graphic nature of the room. While chasing a couple of our kids I turned around to see them playing a video game of some sort. Upon closer inspection I realized that yes, that is a cervix with sperm racing to the finish line (the egg). I realized this at right about the same time as another mother who was there and we both started to giggle quietly behind our children, not wanting to make a big deal about it, but thoroughly enjoying their screams of "go! go! the other sperm is going to win!". Ah Science World, always an adventure.
