Tag cloud module extension

Hi everyone, I've recently set up a new document library on our website making use of the Tags feature in eDocman - you can see the page here www.hivlawcommission.org/index.php/elibrary . I'd like to add a module in the left sidebar containing a 'tag cloud' to enable users to filter through the documents. Can anyone recommend a solution for this? Are there compatible extensions in the Joomla extension directory? Any insights would be greatly appreciated.

Cheers,
Ian

Ian hired us to develop this module and he agrees so share it on forum. So if anyone want to use the module, please get it here and install it to your site .

Thanks Ian so much !
