This one may not be too fair, but I'll post it anyhow. Does anyone know what this is? Post your guesses in the comments section below.
UPDATE: Okay, no takers. It's the ceiling of the Cincinnati Museum Center. The building was once a railway station, and has this really cool half-dome shape. I was hoping someone would guess some type of festive plates, because I thought that's what they looked like. Anyhow, I have posted more museum photos.
