Recent surveys of multiplicity fluctuations, transverse momentum fluctuations and two-particle azimuthal correlations are presented for several collision systems as a function of centrality and transverse momentum. Both multiplicity and transverse momentum fluctuations exhibit a power-law scaling as a function of the number of participants that is independent of the collision system. Although these observations are consistent with critical behavior, the critical exponent {eta} measured using azimuthal correlations is seen to be independent of centrality and collision system. Also observed in the azimuthal correlations is a displaced away-side peak in central Au+Au collisions when the pairs are restricted to low transverse momentum.
