A lot of good courses mentioned that fit the bill...thanks guys.
From my perspective, the feature that I look for is how the artificial contours (dunes, hollows, etc.) are tied into (or not) the playing areas.
In that regard, one of the biggest disappointments I've seen is Whistling Straits, where conical mounds spring and pop up like a bad case of acne, but without any logical or natural tie-ins to support it.
Fake hollows seem even trickier, and I've seen very few who do this right.
You can tell a bad unnatural hollow, because right at the bottom of it you'll likely find a little drainage grate. What that tells me is that the larger picture of water runoff wasn't considered effectively in deciding to place the hollow.
As far as dunes, not much looks worse than rows of big mounds just down the sides of each fairway, but very little tieing in to the fairways or greens. They routed the course at Birkdale between the dunes like that, but that's an exception proving the rule.
Give me a ballsy fake design that takes a teeshot up and over a dune like some of those Lahinch pictures, and I'll show you an architect at least trying to approximate the adventurous spirit of the linksland, as well as the look.
