Grant,
Here's one I did called waterfall:
PAR 3 – Waterfall
Inspiration – Waterfalls are an iconic natural feature, and not totally unheard of on the golf course. This interpretation adds a miniature golf character by placing key elements of the hole over the stream before and after the waterfall, and by adding fairways to each side of the falls that can be used to play ground shots around the hillside to the green.
Golf Experience – At the tee, the player is presented with a short (no more than 100 yard) Par 3 from an elevated tee to a narrow green below. The tee box is set on an earthen “bridge” platform over a stream that drops over a ledge to a pool a moderate distance below. To the left and right, fairway leads from the level top of the hill down and around the hillside to the green. The fairway is canted outside to in, and ends at green side.
The green stretches from the left and right arms of the fairway, across the stream, through another earthen “bridge”. Front and back, the green falls away to collection areas. The green is divided into three sections. The left section slopes from the center then mostly levels off to the edge, with the exception of a bump middle left that deflects balls rolling on the green from the fairway, creating an interesting pin placement “A”.
The center section straddles the stream, this section is effectively level. Pin placements here are protected by the water back and front, so the level green rewards those so daring with a good putt. Also, players who are left with a pin right or right with a pin left are given a bit of respite judging the break through the middle.
The right section runs downhill center to the right edge, but also includes a spine bisecting the section side to side. Holes in this section reward players who can find the correct half (front or back) on their tee shot.
Strategically, this hole presents a number of puzzles dictated by pin placement. Pins left and right can be attacked with an aerial or ground shot. The ground shot around the fairway should play to the proper side of the green, but controlling placement on the green is not possible. The aerial attack is also available, and shots long or short have generous if collection areas for recovery. Exact placement is possible, but less well placed shots may find water.
Holes pinned in the center section can only be directly attacked through the air. However, the green is not deep, and shot on line but long or short will find water. Shots left and right, whether pin high, short or long, can be played from the collection areas.
For players concerned with the water on holes pinned center, the ball can be played on the ground, taking water out of play, but the second shot must accommodate the green features.

Personally, I think the major weakness of this design (other than the presentation) is the Mini-golf nature of the hole. But having thought about the playability, I really believe it would be fun, over and over. And, with the center of the green arguably the most defended location, this design turns on its head some of the conventional wisdom in golf: the center of the green is "safe".
After I submitted it, I thought some more about the tees and concluded that if multiple tee boxes are aligned along stepped falls, the hole would be more interesting. One thing I was never able to do to my satisfaction was figure a way to make the hole play with the fairway effect and the green at an angle, so that club selection came into play based on pin location. In the end, I thought that was less important.
