Launched on 20 November 2004, the Swift Gamma-Ray Burst Explorer is the most capable rapid response space observatory ever used for astrophysical exploration of the Universe. Swift is primarily designed to discover and follow Gamma-Ray Bursts (GRBs). In that role it has already doubled our knowledge of these strange and enormous explosions at the edges of the Universe. Swift has shown us surprising results about the process of black hole formation, triggered measurements of the chemical makeup of the Universe less than a billion years after the Big Bang, and raised doubts about the behavior of the highly relativistic shocked material that creates the GRB 'afterglows'. I will review the Swift discoveries of the past two years, and cover the non-GRB work deriving from Swift's rapid response abilities.
