Braid will be on exhibit, with other interesting games, at the Laboral Art and Industrial Creation Center in GijÃ³n, Spain. The exhibit runs from March 30th until about June 30th, 2007. Here is the main web page for the event.
Babelfish does a pretty good job of Spanish-to-English translation, and I quote:
The Gameworld exhibition explores videojuego as art form and presents/displays contemporary work examples of art related to videojuegos. By means of that double line of investigation, the exhibition explores the videojuegos and computer games like entertainment, form of art, agent of innovation and cultural force.
So, score another point for the Games as Art team. Laboral has not yet posted the full list of games in the exhibit; I’ll announce it here when they do.
