I have already posted on the book Digital Art. It summarizes key works and theoretical aspects of works of digital art (including photography, sculpture, web-art, etc).
There is a section on videogames and gaming (as source of inspiration and material suport). The connection between games and digital art is obvious and really strong. The overall impression is that videogames are not more broadly recognised as an art form exactly for being so successfull as an industry.
Electroplankton, by Japanese artist Toshio Iwai, is probably the best example of a videogame that could be easily placed on an exhibition (along with some Llamasoft works). Most interactive digital art works could be called non-games. coincidentally, my project share similarities to some of the works presented in the book.
Coincidences like that have two sides: in a pessimistic way, that makes me think that the project is not so original and unique as I hoped it to be. But, looking on the bright side, that also shows me that other practitioners trailed similar paths - so there must be at least something interesting about it.
