Figure I would define the motif of this topic to start things off.

First result is a Packed Elipse; left background as transparent so it may not look so pretty.

OK; turned the Circlism into marbles. Used a lot of blendings to include both BRL as well as Inkskape's Marble matertial bitmap filter along with a few other things (i.e., don't ask). lol

Final version is a cheat (i.e, DAP Christmas preset I created a few years back). Used 4 separate passes and blended via the GIMP of course.
