The story gave an inspiration to make an artifact about narrator’s experience Lijiang. In the last paragraph of the story, the narrator stares at the holographic fishes and thought about his experiences. Fish usually represents dream and something untrue, it might be cool if we make a holographic pond in somewhere else. The pond is full of water, and when people want to look at the fishes, they can throw down fish foods, then “fishes” will appear.
I personally think this idea is very relative to the story, but not as unique. Many interactive artworks today uses projection and autostereoscopy today to strike visual performance. Problems such as technological problems and interaction accuracy might appear, it requires forward research to fully support the idea. The idea is still too vague.
