In this talk we will construct an infinite dimensional cellular complex C that can be seen as a generalisation of the associahedron for an infinitely sided convex polygon. To give an idea, the vertices of C are in bijection with all possible triangulations of the circle which differ from a given one only in finitely many diagonals. The complex C is contractible and its group of combinatorial automorphisms is related to Thompson's group T, which is an infinite finitely presented simple group of homeomorphisms of the circle.
