The dynamic subject of the Galactic center is driven mostly by high-resolution imaging both in the continuum and in the spectral line modes in a number of wavelength regimes. An attempt has been made to give a short overview of recent observations in this region, as follows: 1) Unusual characteristics of the population of molecular and dust clouds within the inner few hundred pc of the Galactic center. 2) Large-scale magnetic structures within the inner 100 pc of the Galactic center and the possible evidence for their poloidal configurations -unlike that seen in the disk of the Galaxy. 3) Stellar kinematics in the bulge and the possible evidence for a massive central source at the dynamical center and its examination as a gravitational lens. 4) Morphological and kinematic evidence for the Galactic center wind interacting with stellar wind associated IRS7, a mass-losing supergiant lying one light year away in projection from the Galactic center.
