glatt, you were right, there *are* two seams.
The cube is made from 4 prisms.
Then I got to thinking about the dichroic coating and if it's just on the internal faces or all sides of the prisms.
{I think it's just internal}
...then I wondered which faces are tinted for which colors.
...then I tried to imagine assembling one and keeping the colors straight
,,,then I boggled at the tolerances required to make such a seam optically perfect.
...then my brain turned into a torus.

I doubt the prisms have a Dichroic coating. They are recombining the three colors

But anyway, that's the coolest paperweight ever.
