This is a fairly normal effect, due to the fact that when the pen arm moves 90 degrees it covers more egg surface than when the egg turns 90 degrees.
For a chicken egg, we would recommend:
1. Positioning the pen motor roughly halfway up and down in its slot
2. Stretching your image to about 150% of original width. According to our user ragstian 148% is more correct. ;)
Alternately, you can use the Stretch extension to perform the stretching– it will help reduce distortion at the edges. For the Mark Twain egg in our kistka demo ( http://www.evilmadscientist.com/2014/electro-kistka/ ), we used the stretch extension with a stippled drawing, and found that it worked extremely well.
I’m glad to hear that you’re excited about the kistka– it’s a neat tool, and we’re really looking forward to seeing what people do with it.
