Convergence and cross-pollination of cultural fields is probably the most common way of inventing new art forms. Game art is one such intersectional example. Basically it is art inspired and/or expressed by computer games. It has been a field of experimentation for about a decade but apparently it is gaining ground.
The development of the field follows a well established pattern – photography was quickly embraced by artists and so was video technique. The computer game genre also has everything it needs to be used for artistic expression. Not only technically and visually; to many people born in the seventies and later allusions to classic computer games are probably as relevant and meaningful as literary references. Furthermore - the fact that it is a combination of two fields opens up for an explosion of new ideas and unexpected innovation.
