The Wooltru mystery

The building on the left in the photo backs onto Cape Town City Hall and is know as the Wooltru building in Corporation Street. While Wooltru is a huge company that (as I understand) is the cash shell of several other large corporates I've found it extremely difficult to find much useful information about them on the Web.

They have no Wikipedia page and their www.wooltru.co.za site doesn't work and hasn't been indexed by Google. With the exception of a handful of financial articles on fin24.com there really doesn't seem to be much information that someone like myself (who is largely ignorant when it comes to cash shells, reverse takeovers, and other business strategies) would find useful.

Please, if you know more than I do, would you mind leaving a comment to explain what Wooltru is about and how this all works?
