Traditional artworks like paintings, photographs, or films can be reproduced
by conventional media like printing or video. This makes visitors of museums
possible to purchase postcards, posters, books, and DVDs of pictures and/or
movies shown at the exhibition. However, newly developing arts so called
interactive art, or new media art, has not been able to be reproduced due to
limitation of functionalities of the conventional media. In this article, the
authors report a novel approach of sharing such interactive art outside the
exhibition, so that the visitors of the museum can take a copy to home, and
even share it with non-visitors. The authors build up their new
projector-and-camera (ProCam) based interactive artwork for exhibition at
Museum of Contemporary Art Tokyo (MOT) by using Apple's iPhone. The exactly
same software driving this artwork was downloadable from Apple's App Store --
thus all visitors or even non-visitors could enjoy the same experience at home
or wherever they like.
