I actually did the Cowboys GC putting green as a star, as in their logo, not wanting to get cheesy on the course. The first superintendent stopped mowing the points before the course even opened.
As many know, I also did the footprint bunker at Giants Ridge, but it really happened to fit the hole and ground. There was some discussion about it, but most golfers love it, and now that the logo inspired by it has sold a bazillion shirts, I think the Owner is quite taken by it.
The short version is that there is a limited amount of wiggle room for whimsical design, and most of it comes on resort type courses. If that green (or my bunker) was the only thing golfers talked about regarding the course, it would be a bad thing, but if its a good course with one or two whimsical features, I don't see anything wrong with it.
Its just resort golf, after all.
