Invisible colours

This afternoon it was make or break for one of the projects: we had a special gathering to have a look at the glass dodecaeder (yes, I had to look it up too). The idea is that it makes visible with the naked eye the flares that can be seen through a camera lens. And it actually worked! Sometimes the dodecaeder is completely transparent, but when the light falls on it in a certain way, all these colours appear.

However, the problem is that it is not allowed to have any lights or reflections in red or green around the train platforms, because it could confuse the train conductors.

But there was good news too: it may be that the experimental pigment paint can be produced, with the help of a special lab at the Technical University in Eindhoven. So now we'll know in two weeks time whether Nicky can paint the platforms with this magical material.

Adventure

Nicky Zwaan came by today discuss her project, Invisible Colours. It is an exciting work, because the materials she is going to use are highly experimental and never used in this way or on this scale. The problem with experiments is always getting a guarantee by the manufacturer. And then trying to persuade the commissioners to accept the work without any guarantee. So now, in China they’re doing a durability test, but even if the results are positive, we are not sure if a guarantee is possible. What an adventure this project is!
