Scroll through a list of the games and click the spacebar to play one here. On his blog, Barr writes about being "on the precipice of a game that will outlive you:"
"One thing about the longer games in the series, specifically '100 Years of Solitary' and 'One Millennium Avant-Garde Band,' is that they will outlast us. That is, when you start the game you're at the beginning of something you can't really figure on seeing the end of – you'll die. So there's a weird kind of 'memento mori' going on in those games that I hadn't really given a lot of thought to at the time. It's funny in particular to me because the games do have specific endings."
Barr created these games in a collaboration with the Marina Abramovic Institute, a crowdfunded, perpetual art space cultivated by artist Marina Abramovic. If you're into the eccentric, or want to be a part of something that will outlast your own life, check out Durations or some of Barr's other strangely engaging games here.
