I once saw a person's blog avatar which had the yin yang icon, but with the two components separated into their own, perpendicular planes. The components each rotated in their planes, in a way that they touched but did not occupy the same space. I thought to myself, "I can one-up that."

So I made a 3-component yin-yang-"yong" and set the components on three perpendicular planes. However, this arrangement creates a singularity at the origin; a 2-dimensional yin-yang-yong won't fit properly on 3 perpendicular planes. So I re-designed the components to fit.

Then I noticed that the system was a bit out of balance. It looked cool enough, but the asymmetry was bugging me. Finally, I realized I could double the entire thing by creating a copy and inverting it in all three dimensions, and still, no two components would occupy the same space! The system still has an overall nonzero vector of rotation -- another form of asymmetry -- but there's nothing I can do about that with this planar arrangement.

Edit: Apparently "yong" actually means something. I only chose the word for the third component because it sounds good after the words "yin" and "yang".
