Hi,
Why don't we justify our wall papers so far.

I am ready to justify mine right away.

The wall paper is an ad of the OS - NOT of the Designer, the Artist, or Freelancer, or whoever it may be (hobbyist in my case).
So we shall all forget about our Ego ('leave it on the hanger' at the lobby) and do everything in benefit of the users.

Justification
The attached picture represents a spaceship traveling on a perfect orbit (the exact front and rear view suggest this) - or this may mean also that the person drawing the picture cannot make 3D designs, but this is another theme.
Yet I am not sure that making this 3D will make it look better and will improve the message.

The form of the ships is straight and clean (there are no 'projections' exposing the ship to dangers when making complex manoeuvres) - respectively to the OS there are not projects where some .exe Troyans and viruses may stick up (or at least the risk is reduced to acceptable limits).

The perfect orbit suggests perfect control on the machine (by analogy on the computer through the OS) - reliability, flawless operation, thrust in the designers (respectively in the software engineers having developed the OS), etc.

The principle of operation suggests that there is no way of running out of fuel (the 'fuel' is all around you) and by analogy to the OS - there is no way of remaining without software - software is 'all around you' and there are always people who are ready to help you with pleasure.

The straight lines representing the two energy sources of the vacuum suggest (as straight lines) sustainability, power and personal dignity, and feeling of traveling, of doing the things by yourself and managing with the problems.

Extracting the energy of the vacuum suggests that everything is possible if you know what you are doing.

Light is dominating all over the picture and yet the contrast is reduced to be convenient for working (by the way this is not so easy - you may try it).

Light is the classic symbol of enlightenment, of knowledge, and creative thinking and so is the OS and the Apps and Browsers going therewith.

The dominating blue color is typical for Fedora distros - this is obvious - and the Fedora logo will go well on it.

The 'partitions' made as a result of the 'plasma beams' are convenient for placing the icons on the desktop and grouping them by theme, purpose, etc.

Hoping that I am not boring,
Thank you for the attention
Regards
