Apparently, Nintendo Floor Vision is digital art executed by a button-less DS and floor lights. The exhibit is featured at Shigureden. From the article: "According to Moz la Punk message board member Tadashi, it’s for an art exposition, where the DS is used for poems and poem writers. Judging by this comment and the press release it seems as though all together the art exposition is essentially historical and that poetic interaction via the special DS takes place."
Could there be more?
