Heat Flow (The Feather Ring)
I glued two small round neodymium magnets to two carbon fiber tubes and put a spring in them each, then attached the springs to an aluring by means of another magnet, as I did not have it in steel and alu is not magnetic.
The whole thing is now fixed to my heater with another magnet. Everything is variable because of the magnetic fastening according to Gusto e.g. the position and slope of the springs can be changed.
I used black colored goose keel and selected two semi-similar feathers. The thermals of the heater (as I said, it is winter) moves the bushy hairs and thus one can see as a nice side effect whether the heating is on.
The size is about 60cm (wide), 21cm (high), 5cm (deep)
