In a small dunal landscape next to a maple tree, a pole covered in solar panels powers the webcam hosted on its top, recording imagines of life passing by underneath it. Frames from the footage are then uploaded on a specially created website.
On the pavement, a poem in several languages engraved in granite pays homage to the dead.
