Charney, Crisp, and Vogtmann defined an outer space for 2-dimensional right-angled Artin groups. In this talk I'll describe a construction of a contractible subspace of that outer space on which the pure outer automorphism group of a 2-dimensional right-angled Artin group acts properly and some of the properties of that subspace.
