This futuristic glass encased art museum, the largest in Japan, houses only temporary exhibits. From the article:
The museum's main peculiarity is that it will hold no collection of its own, making it the world's largest art center living on temporary exhibitions that range from acclaimed foreign work to pieces by lesser-known emerging artists.
Oddly, the architect plans for the museum to display a large portion of art via flat screen TVs connected to the internet once copyright hurdles can be cleared. Will people actually pay money to view the internet at a museum? link
