How can you tell if it's New Media Art? Here are some tips.
(New Media Art in the Aughts is what web art was in the 90s, installation art was in the 80s, and performance art was in the 70s. That is, largely oblique and inaccessible unless done very well.)
This handy list was put together by the Near Future Laboratory, a "think/make design & research practice focusing on digital interaction designs based on "weak signals" from the fringes of digital culture, where the near-future already exists."
