Apply a liquid rescale to a set of images to construct a gif of distortion.

distort.py

#!/usr/bin/env python3

# USAGE NOTES
#
# - You must create a directory called pngs
# - Once you have created your images you must run the following command to create a gif:
#     convert -delay 1x8 `seq -f pngs/out-%03g.png 0 1 40` -coalesce out.gif
#
# This script depends on imagemagick, liblqr (liquid rescale) and wand for python (pip install Wand)
