ABSTRACT
A color photocopy: now almost old-fashioned in terms of reproduction tech-
nique. In 1983, Alle Hosper and Lodewijk Baljon produced a plan for the
much debated new Markerwaard, meant as the final stage of the Ijsselmeer
polders project. After much thought about how to present the plan for this
polder, they finally decided to insert a color copy in the booklet [14-1]. It was
made on the only color copying machine in The Netherlands at that time-
at Schiphol Airport. They deliberately chose this particular medium-in those
days rather advanced-because, as Baljon stated:
Hosper used the computer for the first time in 1992 for a project for an instal-
lation for temporary gas storage. The machine in question used computer-
aided design (CAD) software that allowed corrections to be made more easily
[14-2]. However, it soon became obvious that the computer was also suitable
for other activities in the design process. Barely ten years after its initial
use for drawing, the computer was being used for almost all presentations.
