Four years after commissioning, experiments at the Relativistic Heavy Ion Collider RHIC have collected an unprecedented amount of data on nucleus-nucleus collisions up to $\sqrt{s_{NN}} = 200$ GeV. The current discussion of these data focusses mainly on three discoveries: i) the strong degree of collectivity of the produced matter, seen in the measurement of elliptic flow, ii) the strong suppression of leading hadroproduction characteristic for the high density of the produced matter and iii) first indications for high parton densities attained in the initial state of the collision. In this talk, I discuss the current understanding of these findings and to what extent they provide us with novel ways of testing QCD at high energy density. I identify the main open questions and I discuss how they can be addressed in future experiments at RHIC and at the LHC.
