The Magnetism in Massive Stars (MiMeS) project aims to explore the origin, characteristics and physical impact of magnetic fields in hot, massive stars. Supported by 3 large observing programs corresponding to a commitment of over 1500 hours of telescope time, the MiMeS collaboration is comprised of an international team of over 50 observers, modellers and theoreticians located in 15 countries. This talk will review the motivation and structure of the project, then describe a few recent results selected from: first statistical results from the MiMeS survey and the inferred basic characteristics of massive star magnetism; confrontation of theoretical predictions of the influence of magnetic fields on internal circulation and mixing of OB stars; direct observation and modeling of stellar wind channeling and confinement in both B and O type stars; and ongoing efforts to test hypotheses that weak, heretofore undetected magnetic fields are at the root of cyclical variability inferred to occur in the winds of most, if not all, OB stars.
