This is just arts and crafts, but it does have a great definition of the arms of a multimer (the image itself i did not take but it is part of an ongoing effort to see what types of image processing provide the best data on number of peaks along the length of each arm.  So this is more science illustration with just  a tad of science. The original had some label in it which i patched with photoshop, then flattened, then exported as tiff, imported into CorelDRAW 19 where i did “texture sculpture”, relief at 10o and detail 100, smoothness 100, and depth 100.  This image was saved as a tif, opened in photoshop and a custom color gradient applied.   The ring multimer is pink.
