I remember seeing this sculpture in Darmstadt and I saw it as a geometric structure, a circle filled with cubic shapes. It is located in front of the Staatstheater at the Georg-Büchner-Platz. It’s called Grande Disco, by Arnaldo Pomodoro.
The landmark of Darmstadt can be seen in the middle, a pictorial rendering of the Hochzeitsturm (wedding tower) which is also called the Fünf-Finger-Turm (five finger tower). This tower is a superb example of art nouveau architecture, a work all by itself.
However, when I prepared this post and I looked at the thumbnail of the photo, i.e. a very small version of the photo, all I could see was a flower.
