After reading a reply that included a crystal ball => http://community.logos.com/forums/p/54439/399163.aspx#399163 searched Logos 5, which found an article, but the hyperlink to peep stones does not work:

Edit: the peep stones link does not work in Logos 4.6a Beta 2 on Windows 7.
Also looked at screen and noted Logos 5 looks a bit different (X to close tab has moved) so publicly posting above screen shot could lead to more question(s).
Do like help suggestions for Search on screen.
Keep Smiling
