Lostery, a sound/visual installation dealing with gambling and games of chance, evokes the socio-political impact of the notion of luck on individuals (whether in countries at peace or at war, in a rich or poor economic context, etc.). The abstract black and white graphics evoke mechanical cogs, where we fall into the trap of double or nothing. The borders are erased between the objects and sounds of the real world (poker case, chips, casino sounds) and the imaginary world (artificial objects, three canvases, projection), giving way to an intense kind of poetry.
