In the wind-tree model you play billiards on an infinite table which is the complement of a set of square obstacles. We consider a wind-tree model with arbitrarily placed obstacles and show that for a (Baire) generic set of configurations the wind-tree dynamics is "nice" : ergodic, minimal, with infinite ergodic index. This is joint work with Serge Troubetzkoy.
