Skyline is a permanent artwork in the council chamber of the southeastern part of Amsterdam. Tee and Niessen have created a secret language with which they build a skyline, made out of silkscreen prints in a system using 6 patterns and 6 colors. First, Tee made drawings of motifs that are characteristic of the Bijlmer, such as shopping carts, African symbols and footballs referring to the Ajax-Arena. Richard Niessen then converted these drawings into patterns and signs. With a legend the signs can be decoded into well-known names of streets and buildings in the Bijlmer. The wall, which gives the impression of totems or flags, is beautiful in its details and it has a great impact as a whole.
