LOL. Who would have thought that Rob was going to update the page at
the same time that I posted to you guys. The actual 'mystery object'
that I was referring to is the first one on THIS page.

Enjoy the current website, but if anyone has any insights to the object
that I was originally referring to, I'd be interested.
