I am looking for a nice 3D art for my PhD cover (non commercial use).
The art should contain certain aspects, I added a 2D draft here.
What should be visible on the Figure: There is a (proteine) structure and at two positions there are specific markers, where spins are flipping (the arrows). Now the distance (R) between the two markers can be measured, indicated by the arrow.
The double arrow with (R) is not absolutely necessary, but what would be cool in some way to show that the two markers are different, as you can see by the different flipping arrows.
