  A variety of scientific results have been achieved over the last 10 years
with the GROND simultaneous 7-channel imager at the 2.2m telescope of the
Max-Planck Society at ESO/La Silla. While designed primarily for rapid
observations of gamma-ray burst afterglows, the combination of simultaneous
imaging in the Sloan g'r'i'z' and near-infrared JHK bands at a medium-sized
(2.2m) telescope and the very flexible scheduling possibility has resulted in
an extensive use for many other astrophysical research topics, from exoplanets
and accreting binaries to galaxies and quasars.
