Floating interior of Norma's House from 1994 Original Production
The floating refers to the interior of Norma's house. The entire set was raised and lowered as needed. If you watch the follow video...at the 26:28 mark you see a pretty good view of the complexity of the set. If you watch the entire video you'll set some of the other sets....in the new production there are no sets as such, just props like desks, tables, chairs...all moved onto stage as needed. https://www.youtube.com/watch?v=BQR74a4P3nw
