I'm working on a project where I will have vertical partitions between
two horizontal shelves. I want these partitions to slide out and if
possible even pivot (i.e. 90 degrees on the vertical plane) so that
they can be viewed on their broad surface rather than their end surface
(i.e. what you will normally see when they have been slid back into
place). Maybe I can ascii-art this (I am sure proportional fonts are
going to screw this right up -- looks good in a mono-spaced font):

--------------------------
| + + |
| | | |
| | | |
| | | |
| | | |
| + + |
--------------------------

So that's two vertical dividers in a box, where the "+" are slides that
the dividers ride on so that they can be pulled out full extension.
Ideally, once the dividers are pulled all the way out, they could pivot
90 degrees left and right. The pivoting is gravy. What I am really
looking for are the slides. Anyone know where I can get them, or what
they are called?

If I didn't need full extension and (with luck) pivoting, I could just
easily route a couple of dados in the top and bottom shelves to achieve
the action I am looking for. Hope this helps explain what I am looking
for.

Any help appreciated, thanx!
