I went to a hatsune miku holographic performance at a festival concert here in Tokyo a few years back. The crowd was into it and it was a lot of fun. Visually, it was totally convincing from the center of the floor at mid-distances. There were other characters who performed, they had costume changes, special effects, etc... It's a 2D effect but at concert distances, you can't really tell and the lighting of the character convinces your eyes. There was one point where she put her foot up on a monitor speaker and my mind was blown until I realized that the monitor was part of the hologram too. It had been sitting there by the floor for the whole song waiting to have her put her foot on it.
