Can we have a spirograph feature within? i think about the old toy i did a search here https://sourceforge.net/directory/?q=spirograph, it could be fun if we implement a feature like this in both vector and raster,for more flexibility versatility.

Ther'es a fun webversion to play whi it : http://nathanfriend.io/inspirograph/

Hey. This looks like a really fun idea. I am not sure how hard it would be to add something like this, but I love the idea!

Once the python scripting is done this shouldn't be too hard to implement an algorithm programmatically.
Something similar done in wxPython, but it doesn't have the fancy stencils and mouse functionality. The GUI/Mouse Drawing/Steps functionality would need done tho.

Also the GUI might look more native to krita written in PySide/PyQt.
