Tip
Script formatting results from the HTML export of KTurtle.
Note for translators
If you want to translate the scripts the best way is probably to create the script in KTurtle, export it as HTML, and insert the exported HTML in the respective Input templates. Alternatively, simply leave the scripts untranslated. A simpler solution using the syntaxhighlight tag is currently being investigated
Koch curve
This is a fractal curve. You can find more information about this at Wikipedia.
Logo script:
