Me too :-)

I've written a script which uses GDAL, mdenoise and ImageMagick to
create hillshade maps from SRTM which are more appealing than the
standard hillshade computation images. Python is used as a glue
between the commands and to provide a user interface on the command
line. You can have a look here [1] for inspiration ...
