Iconic Van Gogh ~ 'Starry Night' (1889) depicts the view outside Van gogh's sanitorium room window at Saint-Rémy-de-Provence, at night. Made even more famous by singer, Don McLean's 1971 song, 'Vincent' (Starry, Starry Night). I've seen the original ~ these stars throb with energy!
This is a picture of Wolfgang Laib in 1992, sifting hazelnut pollen for an installation at New York’s Museum of Modern Art. The pollen was collected by Laib from the woods around his home and studio near a small village in southern Germany.
