A few years ago I had a conversation with a staff member from Uytenhaak Architects about concealed texts in Amsterdam, relating to my own work ‘stoned forever’, which is integrated in brickwork in the Olympic Quarter. He said that there is a text in Morse code incorporated into the Droogbak (1989), a residential building by Uytenhaak: ‘Deze muur staat er niet’ (‘This wall isn’t here’). It is located close to the railway line. Rudy Uytenhaak later told me that this was his last opportunity to protest against the acoustic fence that had to be constructed for bureaucratic reasons.

Old parking garage turned canal bar.

The fence around De Nederlandsche Bank on the Frederiksplein is a true optical experience. While passing the building, a rhythmic, dynamic pattern appears and disappears in the trellis of the fence. The figures on the sides of the rails were designed in 1992 by artist Peter Struycken, a pioneer in the area of environmental art and generating computer-program based image, light and colour compositions.

Since I was a child I always loved to go to the aquarium in Artis. This mysterious world that we will never really get to know makes me wonder and raises questions. I like this mysterious world. It’s a place to relax and think things over.

At the end of tramline 7 and 14 there is a huge bridge on concrete pillars. These pillars are one of the few places in Amsterdam where it’s legal to spray graffiti. My work is very much influenced by graffiti, so I love to come here and see what’s going on. It’s a very dynamic place, so one day it can be awful and the next day amazing but it’s never boring.
