Context can be an entertaining thing. And also change meanings of things significantly like when I looked at the picture first and then looked at it again after reading the article.
Initially thought maybe it's a door opening to a dark room where the character is. Or maybe a spotlight and they're on stage. After reading the article it's now a movie projector (because that totally makes sense).
Totally is a projector of sorts. Could be all that other stuff as well, being projected.
