ABSTRACT: This is a continuation of my  January 25 talk  at this seminar (an effort will be made to make this talk self-contained).
We will concentrate on cluster algebras of finite type. Their classification turns out to be yet another instance of the famous Cartan-Killing classification. We will discuss an explicit construction of a cluster algebra associated with an arbitrary finite root system. An important ingredient of this construction is a "generalized associahedron" associated to any root system in a recent work by S. Fomin and myself.
