The Clawpack Gallery is available only for the latest release of Clawpack.
The Gallery shows results obtained by running many of the examples that are included with Clawpack, from the directories
and also from
which must be obtained separately from the main installation of Clawpack, see Clawpack Applications repository. The directory $CLAW/apps/notebooks contains a number of Jupyter notebooks that illustrate various aspects of Clawpack. Many of these are also visible in rendered html form in the Gallery of Notebooks.
