This, much like all of the videos in our Graphical Python Effects series is made using the programming language Python, with a bit of help from the Python library Pygame (for the graphics) and our favourite noise algorithm Perlin noise (for the colours)!

If you are interested, the code for this effect is available on our GraphicalPythonEffects repository on GitHub: github.com/PycraftDeveloper/GraphicalPythonEffects

Finally, this video and the source code is absolutely free for you to use in your own projects!
