This Python script takes a set of Healpix maps (in FITS format) and produces an animated .gif file with Mollweide projections of the maps.
The tool must be used from the command line. Each FITS file must be preceded by a title, usually enclosed within single/double quotes:
$ animate_healpix_maps.py 'First' 1.fits 'Second' 2.fits

The following animation has been produced using the maps delivered by the COBE/DMR team for the two 31 GHz channels (download them from here). The command used to produce the .gif file was
$ animate_healpix_maps.py \ -s 0.75 \ --pixel-distributions \ -o dmr_31.gif \ 'DMR(31a)' dmr_31a_imap_4yr.fits \ 'DMR(31b)' dmr_31b_imap_4yr.fits
