All components of the wallpaper need to be made by yourself or used with the permission of the original author.
The background needs to look nice with a high resolution (1920x1200 is the minimum standard).
Your creation is protected by copyright and we will not use it without your consent, yet it would be nice to be able to try out any wallpaper design ourselves to know if it actually works as a background, as it's extremely hard for us to tell from just looking at some picture.
Also note that for the winning design, we'll require access to individual layers and/or vectorial components of your wallpaper.
Since we might choose to include more than the default wallpaper in Netrunner 17, there is a good chance that we will like to buy other designs, too. Since there is only one winning prize of 549,-EUR, we may choose to deal with any other artist on an individual 1-to1 project base.
Have fun and please do not hesitate to ask questions.
