Rene Knip's letters are architectural, built and constructed rather than drawn or written. And the architectonic nature lends itself very readily to use in real architecture: in buildings, on walls, as floor tiles, etc. Knip takes inspiration from various existing letterforms left over from the 1920s and '30s, especially those that he has found in the streets of Amsterdam. A bit of Art Nouveau, De Stijl, and Art Moderne. Knip's genius is in melding the letterforms and their immediate environment, making each a part of the other.
