i have been making ritual wind indicators using model airplane technology for years. think of a hand launch glider fuselage with a wire shaft through the balance point, minus the wing and elevator. some of my early ones were made with balsa, bamboo, feathers, and decorative colored thread wrapping with shaft bearings similar to a rubber powered model plane. my recent versions have a colorful soda straw fuselage, vane made from half the bottom of a styro coffee cup (shaped and sanded), with a piece of sharpened pencil for an adjustable nose weight. these things are very sensitive and move in the slightest puff. they only last a few months so i am repeatedly reinventing them. wind seeker icons.
