Floating islands are a popular inspiration for many LEGO builders, and it is easy to see why. They are mysterious and fantastical, and they can provide a great challenge to build them in a way that both supports the model and hides that support to enhance the magical appearance of the finished scene. Nathan Hake does a masterful job of using falling water to provide the support for this microscale floating island with a temple nestled between the trees.
The model is a miniature version of a much larger model built using the same technique to lift the rock above the ground with multiple waterfalls. My only question is… where is all this water coming from? But since it is a fantasy scene, maybe the water flows up to the island instead.
