Noncommutative birational transformations

I will present several examples of group actions by birational transformations in free noncommuting variables. One of examples is related to the talk of V.Retakh on noncommutative Laurent phenomenon, while another (a noncommutative generalization of the Coble action of Coxeter groups of series E) is definitely not cluster.
