Not at the A-Ma Temple, I think. The building behind looks too run down to be near any place of attraction. Yet I can't find many other wavy patterns on Google Earth. *tears hair* Hunch tells me it's not on the mainland part of Macau, but I don't know if I can trust it!
The Dustin praying cap is on the Nam Van Lake side of the Macau Tower, which is strange since it is on the opposite side of the tower as the entrance, and doesn't actually lead anywhere. Is Dustin waiting for Kandice to jump off the tower, and praying for her safety?
OK, now that I'm temporarily out of my coma, here's my take on the "wavy" street. After seeing the actual clip, C/M appear to be on a large square, and you can see a corner of a raised (platform?) or something in the square before they cut away. From what I've read, the "wavy" pattern extends all the way up to the Ruins of Sao Paulo. My guess is that TAR will at least visit the sacred facade during the episode, if only to get a clue. It is, after all, the symbol of Macau. Note Charla is pointing up, maybe in anticipation of climbing the stairs to the ruins (like in Malaysia). Or, maybe not.
Oh, wait, I may be slipping back into my coma again....yes, I feel sleepy.....sleepy......
