If you have any suggestion for the image to be put on the cover of the DC3 report, please share them on-list or send me a private message.
Ideally the image should represent a network and be quite minimal (as you would expect from a book cover) and either in Creative Commons license or of your authorship (in the latter case you will be acknowledged as the image author)
I would suggest something more or less like the picture below. Suggestions are welcome
All the best
