A recent departure for me has been the making of short timelapse videos of the landscape.
I wrote a Python script to interpolate from a set of still photographs, applying a handful of effects (blur, gamma, masking), to a set of output images to combine as frames into a movie (e.g. using ffmpeg). The project homepage is at timelapse.py and sources available directly from github.
Currently my favourite example using this script is Morning at Glen Affric.
