Forest Ambassador - a collection of indie and artgames

Forest Ambassador is a blog maintained by Merritt Kopas which lists indie games, art games, text and narrative adventures and generally the interesting and weird products of game jams. Each game is linked with a little information about how long the game takes, why it's worth playing and, where possible, an artist's statement. 

None of these are exactly high-definition AAA graphical shootfests, but there are some clever and left-field projects worth looking at, plus you can play them all for free! Yay!

I'd recommend Anna Anthropy's 'Triad', Chris Chung's 'Catlateral Damage' and the extreme but educational strangeness of Mike Joffe's 'Benthic Love'.
