This guest editors’ introduction [1] is an experiment as we include photos from all papers on the theme. The rational is, that probably most people will not have the paper copy in their hand. When having the digital version the overview of the papers is harder to manage, that is why we think including the photos helps to make readers curious to look at the papers in the issue. Please let us know if you think this is a good idea…
