Mobile installation of white sheets above an airport gate moves slowly with the air flows higher in the terminal. Walked from Terminal 1 to Terminal 2 in hopes of viewing the advertised art installations at Gate 31, but aborted that plan when the long linear nature of the terminal emperiled catching my departure from Gate 15. There used to be an art installation in Terminal 1, now since replaced by a boring row of carrals for working. (Helsinki Airport, Vantaa, Finland) 20170817
