  We present numerical evidence that supports the theory of quark confinement
based on center vortex condensation. We introduce a special gauge ("maximal
center gauge") and center projection, suitable for identification of center
vortices. Main focus is then put on the connection of vortices in center
projection to "confiners" in full, unprojected gauge-field configurations.
Topics briefly discussed include: the relation between vortices and monopoles,
first results for SU(3), and the problem of Casimir scaling.
