Notes: I passed this chimaeric flying animal a couple of times on the first two days, preoccupied with other things but vaguely aware of something odd. In retrospect I think that part of me realised that the head was in different positions on the two days but my left brain would not let that interpretation become explicit.
On the the third day, a gust of wind made the head turn silently in front of me, producing a strong emotional reaction that was a mixture of startle and joy.
It is so beautifully constructed that there is no sound and even a gentle
wind can get the head turning.
