This is a simple snakes implementation using python outlined in [1] with help from [2]. The example file implements the example outlined in [2]. Python library dependencies are numpy, scipy, and matplotlib.
After cloning the repository, you should just be able to run
python example.py
to see the example problem. After that, run
python example2.py
to see a slightly more complicated shape.
