Fabrice made this mosaic. It sits on the corner of a park in front of an Indian restaurant, near the street. Seems to be some kind of electrical building, maybe housing a transformer.
We saw another one on WillemsParkWeg, next to a tram stop. Another electrical building.
Fabrice has a web site where you can see him, his painting, his drawing, mosaics, and things he has made. www.fabrice.nu. One of my most favorite pieces of art in Amsterdam.
