From guest blogger Nils:
I've built a robot that is hanging from the ceiling on top of a pile pf paper sheets drawing dots. It's part of an art and design exhibition in the Netherlands. The exhibition is about the way we look at things. While a visitor is looking at images of certain objects an eye-tracker records where exactly the viewer has just looked at.
The Lego robot then reproduces exactly these points with a thick marker so you're able to see how objects have been perceived. By this way more and more large scale images are produced and shown on a big wall and it becomes comparable how certain objects have been seen differently. There are much more images, movies and information on my website:http://www.
