This interesting-sounding game (I haven’t played it yet) is described as:

The Graveyard is a very short computer game designed by Auriea Harvey and Michaël Samyn. You play an old lady who visits a graveyard. You walk around, sit on a bench and listen to a song. It’s more like an explorable painting than an actual game. An experiment with realtime poetry, with storytelling without words.

The trial version sounds nice, but the full version ($5 pricetag) adds just one dimension:  the lady can die.

Basically, every time you play the full version, she may die.
