Transformations and metamorphoses play a crucial role; through them, the compositions are in constant flux. They elude everyone; we have to run after them in order to catch them and the moment we have caught them, they may possibly already have a new face. But in contrast to this mobility, there are some surprisingly large orders, orders of lilies. They show the elemental beauty of symmetries and of clear shades of blue. (Gahse, Zsuzsanna, 2013)
