The 1970's seem like a magical time.

My neighbor's groovy "conversation pit" perfectly preserved from 1974 - Boing Boing:

"The Pit (as we called it) is quite literally unchanged since the day it was completed in 1974 -- original pillows, hanging basket chairs, groovy wall graphics, foam-padded lounge areas, stainless-steel mobile, track lights, and all." 

I also will go on record saying the Jungle Room at Graceland is awesome.
