We present first HI maps of the galaxies observed as part of The HI Nearby Galaxy Survey (THINGS). THINGS is a large program at the VLA to perform 21--cm HI observations of the highest quality (~7'', <5 km s-1 resolution) of nearby galaxies. The goal of THINGS is to investigate key characteristics related to galaxy morphology, star formation and mass distribution across the Hubble sequence. A sample of 34 objects with distances between 3 and 10 Mpc have been observed, covering a wide range of evolutionary stages and properties. THINGS is designed to complement SINGS, the Spitzer Infrared Nearby Galaxies Survey. For the THINGS sample, high--quality observations at comparable resolution will thus be available from the X--ray regime through to the radio part of the spectrum. THINGS data can be used to investigate issues such as the small--scale structure of the ISM, its three--dimensional structure, the (dark) matter distribution and processes leading to star formation. We present an HI composite of all THINGS galaxies which displays a stunning variety of structure in their interstellar medium.
