Chaussée Saint-Pierre 210

Game theory is a field at the border between Psychology and Mathematics, where the players in question are not necessarily opposed to each other, but have the choice to cooperate. It applies to situations where several people have to make decisions, and the outcome will also depend on the decisions made by everyone else. Well, as is often the case in real life. These situations were theorized namely by American mathematician John Nash, whom you might remember from Hollywood movie «A beautiful mind» (one where Russell Crowe is not a gladiator). Cooperate or betray? To forgive or to punish? Which is better for you? Come and figure it out. It’s only up to you to decide. Or is it?

Music by


ALEA(s) is an audiovisual collective based in Brussels joining the skills of illustrator FSTN, musician and synth manufacturer Shakmat and visual artist Boris Wilmot.

Born from the will to offer a unique live experience, ALEA(s) delivers boiling, improvised performances created from scratch, mixing drawing, live animation and electronic music.

Surrounded by their audience, the three members are busy creating their show, without any safety net. While the intense, organic electronic music fills the room, the illustrator’s physical implication in his drawings and the hypnotic animations projected onto the big screen unite to finish this well-rounded show.

ALEA(s) performances are often described as immersive, dense and crafted.
