Sorry mate, its not like the 3 distinct types of stonework in Macchu Picchu at all. Except maybe the very top picture in a couple of parts. I've had a pretty good look and didn't see anything like the ones in that Viewzone article. Sorry.
I'm in Peru at the moment and the same 3 styles of rockwork can be observed in every set of ruins I have been to. I've also done a bit of walking round the hills up behind Cusco with Jan and Jesus, who also post on this board, and we've found that these 3 styles are common everywhere. I haven't come across that particular style anywhere here though.
Whilst you may be interested in the subject please read Lomas and Knights "Uriels Machine". I think you will find it incredibly interesting and compelling. They've done some very comprehensive studies and practical experiments involving the stonework Cairns of UK and Europe and done some comparisons with those of Sumeria and even Egypt. It doesn't go too much into the technologies involved in the stoneworking but goes into great detail about the universal measurements that were used (The Megalithic yard), the celestial alignments and the implications thereof.
