I promised you a collage of the process and here it is.
I have talked a lot with this artist, he called me the "photo-lady' as i told him everything about my project.
From the top left to right you see: thinking about the set-up (Tuesday), first paint in (Wednesday), already visible effect (Thursday)
Middle right: Almost finished (Friday)
Bottom left to right: Me in the finished result(look at my hands) and the artist at work (Remko van Schaik)
those are amazing - great pictures showing the process. It takes a lot of planning and visualisation to be able to see this. There are places where they've done this as part of art installations. We saw this one being made http://www.cycle-routes.org/threerivers/ncn7_landmarks/ncn7_artwork2.html - the crane at the bottom that is now vandalised.
