The SFMOMA has a beautiful and far-reaching exhibit called Stillness in Motion — Cloud Cities consisting of ideas and elements that envision our world during the anthropocene. Tomás Saraceno's work is exploratory and immersive and ruminates on the relationships we have with the built world as we wade into our new epoch - the anthropocene. Science, fractals, new materials, space and atmosphere occupy the thinking behind these quietly positive and uplifting forms and investigations. With so much weirdness, narcissism, and negativity nowadays in our politics and culture, this look into a possible future is a welcome surprise.
