“The Egg” aka the Betsy Orb is a sculpture of an ovoid egglike entity wedged between two buildings on Ocean Court in South Miami Beach, close to the intersection of Ocean & 14th Place. It’s named for the Betsy Hotel that it is wedged against.
Update: the Orb is actually a walkway between the buildings!
I last saw the Egg on December 7th, 2019. I was impressed, but somehow expected more.
