I made a recruitment site for Kura-Sushi, replacing MUTEN with MUGEN, planets with sushi, and a solar system. These are made of 3D polygons and can be scaled and flipped over by mouse dragging. The various contents emphasize the awesomeness of Kura Sushi so far. There is also a hidden button. This site was a hot topic at the time. The site was a hit at the time because it was incomprehensible.
