This is a simple experiment I did to create a seamlessly looping texture of coins stacked in a pile randomly, without any intersections or clipping. The method is slow, tedious, requires many steps and manual adjustments, however.
I made this presentation image with Inkscape. All the renders, modeling etc. is done with Blender.
I stumbled upon this add-on for blender that does something similiar far more effectively.
