Is it art?

From March 23-25, the Tate Modern hosted an exhibit to celebrate Yayoi Kusama.

Digital design duo, Helliker and Lewis submitted the Hello Cube as part of the exhibit.  They describe it as "an installation that exists as a sculptural object that you can look inside, see patterns, and an infinity of reflections.

What makes the piece truly remarkable is it's twitterificness.  While the piece responds to voice and physical movement, it will also follow the commands and sent a response to tweets it receives.

Exhibits such as this raise other questions.  In an effort to draw the attention of a younger audience, should classic pieces, such as the Mona Lisa have a social media persona.  If so, does it take away from it being "art".  How does something like that differ from modern reactive art?  Is it more likely that an audience would interact with a classic piece or a reactive piece?  Is reactive art the genre of the future?  Is the art in the reaction or the interaction? Would you tweet with a piece of artwork?
