Dune Ambigrams

Over the last few years I have been developing a love for Ambigrams, and I decided (after/during reading Dune again) I wanted to practice using the Houses from the book. So from the top: Dune, Corrino, Harkonnen and Atreides.

All rotational ambigrams and my own designs. Was also an excuse to practice my currently failing Adobe Illustrator techniques.
