This is an image processing animation. The image's dataframe is sliced in 4 x 4 squares and animated in a given sequence.
The original image I took in 2017 with my Panasonic DMC-TZ10 during a thunderstorm in a sequence of 15 seconds exposure until one got this discharge. Some crop was done to square the image.
Made in Python 3 using Matplolib, Numpy and Pillow libraries.
