According to the official website, a live event of Steins;Gate
has been held at Akhabara Radio Kaikan, where an "artificial satellite-like object" had fallen in the anime. During the three-day event, a model of the satellite has been displayed on the roof of Radio Kaikan just as it appeared in the anime.
