The name of this artwork is "How to meet an angel". There is a lot of controversy about this image because it is placed on top of a psychiatric clinic in Amsterdam.
This is the explanation by artists Ilya and Emilia Kabokov. "It represents the gradual healing process that a psychiatric clinic's clients have to contend with on a daily basis, as well as the active attitude that this requires. For the passer-by it is an invitation to cast one's gaze upwards tot the skies of Amsterdam".
I read on internet that some people don't dare to pass this building anymore.
