Le Fil (Toutain & Le Huérou, 2015)
Le Fil allows communication partners to create a virtual "chatting room." Users can have multiple activities in the room, such as text messaging, drawing and sharing photos and videos. The conversations as well as the shared material stay always available in this chatting room and any user in this room has the access to edit these material. The room is perminant and users can enter and leave this room or use the material any time they want. The room can also be "decorated" by its users so that the room become "theirs."
