A Common Lisp project for creating interesting images with randomly generated functions.
https://piroshky.org/random-function-visualization.html
You can download a binary release for linux here, or you can load the rfv-gui package found in the directory of the same name, and run (rfv-gui:main).
The GUI will save images and their text forms in the specified directory. The text forms will all be put into a file called "functions". Saved images can be reloaded with the Open Image button, this requires that there is a text form with the same name in the functions file.
The Load Text button will try to construct an image based on what is in the text field. If the text is simply a function then it will use the size and color settings as set by the GUI. If the text is a full form, like the type saved in the functions file, it will use the provided values.
