You can use this simple application to observe Koch curves.
The application supports up to 7 iterations.
To support more iterations, caching and asynchronous operations must be included.
Click on the canvas to draw a convex shape.
When the shape is drawn, you can no longer manipulate it.
If you would like to draw another shape, clear it.
If you do not want to lose the shape, save it before clearing.
Set the number of iterations after the shape is drawn.
Click on the apply rule button.
At any time you can change background and curve color by clicking on the color icon.
You can load your favorite saved shapes from your device.
