Ally:
I almost included a reference to Mackenzie's bunkering in my original post, as his bunkering has often been compared to Thomas'. Mackenzie's most famous bunker -- the one on the 10th hole at Augusta National that used to front the green there before the green was moved back, making the bunker a sort of museum piece (nice to look at, but not in play for the Masters at least) -- is sort of oddly out of character with the rest of the bunkering at Augusta, which is very strategic but somewhat plain when compared to the one at 10.
To me, Thomas' bunkering (from the ground) has a very distinct look, and is one of the hallmarks of his architecture work. It's like the very distinct look of a Langford/Moreau bunker on some of their better-known works, such as Lawsonia.
