As a student at Munich International School in the early 1970s I had two years of swimming lessons in Frei Otto's pool pavilion!
It was magic - a kind of fusion of swimming and ying.
I always wanted to tell Otto that it made swimming in chlorine worthwhile even on cold, grey winter days. Even now, 32 years later, on my way home I still sometimes close my eyes and 'swim the sky'.
