Local set up is similar to the non-web version - https://github.com/wizzah/color_shuffle Except, instead of running the scripts to split, process, and stitch the gif, run flask -

export FLASK_APP=app.py
flask run

then go to localhost:5000 in your browser. That's it! There is also code in this project to clear the processing folder between uploads.
