To stabilize the colour of the anchor? I think you put your finger on
the main problem. The main problem is not "colour soup" as I thought,
but rather the colour shifts of the anchor, e.g. when running the
mouse along the track: http://zelea.com:8080/v/w/D?a=5339&b=5340&s
The anchor should be stable. It should not flicker and flash when the
user is exploring. But if we stabilize the anchor colour by forcing
the anchor to the top of the difference scene (sometimes reversing the
order, sometimes not) then whatever we gain in the way of stability in
the vote track might be lost again in the scene. The difference order
will depend on how the user arrives at the scene. No longer will
Georgina (the voter) be predictably on top and Frank on bottom.
Here's a possible solution that would leave the difference order
stable. This tackles the problem directly in the vote track:
a) Do not re-colour the anchor while the mouse is tracking. While
the mouse is tracking, only re-colour the segment beneath the
pointer where the user's eyes are focused. After the mouse is
clicked, re-colour the anchor.
b) Smooth the re-colouring of the anchor (after the click) by
animating it. This will give the user time to understand what is
c) Likewise (though less important) smooth any colour transitions in
the difference scene, such as the loss of colour on selecting
another difference. (Note to myself: when a scene initializes
without colour because of a persisted selection, then animate
that initial loss too.)

We're talking about the right side of this:
It's my favourite votespace visual, too. And the left side is my
favourite talk visual. (Maybe we'll have a talk curtain, too.)
You're right, much of the work has already been done. It shouldn't be
terribly hard to code once we get started.

You're thinking part of the confusion comes from pairing two actors on
stage instead of one? OK. But I think you already put your finger on
the main problem above. After we fix that, we could look at it again.

I don't understand how this would differ from now. Here Frank is the
votespace anchor: http://zelea.com:8080/v/w/D?a=5339&b=5340&s
Here Georgina: http://zelea.com:8080/v/w/D?a=5339&b=5340
You can choose either as anchor in the difference scene.
In a draft scene, the anchor is always the author:
But most other scenes allow you to shift the anchor anywhere without
shifting the scene. E.g. http://zelea.com/w/Sys/p/sandbox
