I've seen several references to the TL120 in my limited
reading about the PMA trade show in Vegas.

At http://www.apug.org/forums/forum45/37332-pma-2007-a.html
I found the following:
3dworld was showing their three-lens MF stereo
camera and viewers, which was totally cool, if
a bit plasticky feeling. Check them out at
www.3dworld.cn. Dave and I were transported back
to memories of the Viewmaster, but with 6x6cm
stereo pairs. There's a lightweight viewer. If
it's not too expensive, it would be cool to have
one of these and a half dozen viewers.

It also gets a couple of mentions at:

Most of the comments are of the "I wonder if it works"
variety but a few seem to understand.
