shuffle-curr-dir.py

"""
   If you have a folder with photos you want to show as a slideshow
   (e.g. with a video projector), and they're obnoxiously orderd
   (by source, event, etc.). use this script to shuffle them:
   `python shuffle-curr-dir.py`
   filenames will retain suffix, but prefix will become some
   random hex. Example: `5f01b70e5fc11f9aa2abf83d466cb482.jpeg`.
   Repeat if you want to reshuffle.
