I can guess. I'm pretty sure I'm right, but without confirmation from someone who has actually seen the prop, all it is is a guess.
The way I think they do the visual effect with the ring: What is perceived as the "rear" of the box is actually slanted at a 45-degree angle. So it's deeper at the top than the bottom. Then, if you lay the ring in there, and light it properly, what looks like a spinning oval is in fact merely a circle.
From there, the eggcrate is mounted so it's face is parallel to the face of the box (which is in fact flat and perpendicular to the floor.)
Really not a difficult visual effect, what's tricky is lighting it so the illusion is maintained.
