Unseen Archizoom

I was trolling around the library, and flipping through some old issue of something, I saw these Archizoom drawings that I'd never seen in any of the "tribute" re-publications anywhere. 

A Rainbow bridge?

a duelling amphitheater?

a lighting grave room?

a huge marble conference table, surprise included?

ok, a garden room

holidays in style

a chair room where you go to hang yourself? 

wait, it's a screen
