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.

Where I buy most of my books and magazines for work. 

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.

The portal between the Leidseplein nightlife area and the Max Eeuweplein is pompously accentuated by a classical looking façade, designed in 1991 by Zaanen Spanjers Architects. On the frieze, supported by columns, the architect has carved an inscription: ‘Homo sapiens non urinat in ventum’ - ‘A wise man does not piss into the wind’. A ‘wisecrack’, disguised in Latin.
