I rummaged through my sketchbook and found these rough drawings, some of my first attempts at ambigrams. The top five (my wife, daughter, wife’s maiden name, and me) read the same when rotated 180 degrees. The bottom two are mirror ambigrams, which read the same left to right and right to left. I’ve added in the Will Shortz ambigram here because it was one of the “client” ambigrams I did at the time that worked out well.
If you want to make your own ambigram, here’s a clever site that’ll generate a very basic one for you — and maybe even give you a feel for how to do it on your own: Ambigram.matic
