Khmer Yantra designs

I have till now not been able to document much on Yant deriving from Cambodia, now i am beginning to research the matter in order to give the Khmer Civilisation the documentation they deserve on the subject, due to the fact they the Khmer culture has a large claim to the origins and history of sacred yantra, and the importance to give credit to them for this.
Below is a clip by youtube member Khmer Civilisation (please visit his page to see all his videos). There are a number of interesting designs on these Pha Yant cloth yantras from Cambodia, wich i personall find to be priceless additon to the info available in the website and blog.
