Here’s another example of a faddish round church built in the later 20th century, All Saints in Wichita. It’s not ugly, but it reminds me more of main deck of a spaceship than a place of worship. It was dedicated in 1965, a year before the debut of the original Star Trek, so it’s probably safe for altar boys to wear red cassocks.

Incidentally, the pastor of All Saints, Fr. Hien, whom I remember as an energetic and cheerful seminarian, is a refugee from Viet Nam who’s had an interesting life (PDF).
