The frog in the orange coat is a self portrait, and my husband is on the far left. Try not to make a fuss if you recognize us in the street.
The floating spaceman-creature in the clouds is from Das Triadische Ballet, a dance that was originally choreographed by Oscar Schlemmer in 1922. He also designed the costumes, which are amazing.
I had never come across it before, although many people I know had already seen it. There was a great reconstruction of the dance that was done in 1970 on youtube. If you haven't seen it, I highly recommend that you get comfortable, maximize the little video below and have a look. I love it.
