You can create complicated fractals from simple shapes with python and tkinter! All you need to do is draw a shape in the right canvas with LMB,
change the amount of iterations (recommended is 50 divided by the number of dots in your shape, though you can change it around and see what happens)
and press button Build fractal!
Shift - press it while drawing shape to create horizontal or vertical lines
Ctrl + Z - undo
Ctrl + Y, Ctrl + Alt + Z - redo
Build fractal - builds fractal from drawn shape
Clear fractal - clears the fractal canvas
Import shape - downloads the shape from .txt file, where every line contains x and y of a shape divided with a whitespace
Export shape - saves the shape to filename.txt file where filename is the text you write before (!) pushing the button
Clear - clears both canvases
