The seating in the Cabaret Theater is quite clever. Wright designed the seating so you can look and talk to the person next to you without getting a crick in your neck. He angled the seating ever so slightly so you can actually put your arm around the person next to you and talk to them and still watch the movie with no neck pain!
In the second photo you can see our tour group sitting in the seats and listening to the architect/docent who is sharing all types of information, including that Wright designed the in-floor lighting system for this theater and it was the first in-floor lighting system ever.
He failed to patent it, but everyone started using it for airplanes, theaters, and more. Wright liked to create items, but was not as concerned about patents.
