Theory of Operation
This effect can be generated as follows:

Convert the image to greyscale.
Partition the intensity space into the same number of partitions as colors
in the color scheme.
Set the intensity regions to their corresponding colors
Increase the intensity of all pixels in the original image (restarting at 0
intensity if overflow occurs).
Go to step 2 and repeat until there are enough sequential frames to make an
animation.

Dependencies
Only Python version 3.6 and greater are supported. This package should run on
any POSIX system as well as Windows 7 and greater.
The following Pypi packages are required:

moviepy
numpy
