Ambigrams are typographical design or artform that may be read not only in its form as presented, but also from another viewpoint, direction, orientation. I was first exposed to ambigrams when I encountered them in Dan Brown's novel, "Angels and Demons". Since then, I have been designing my own ambigrams, mostly as gifts for friends and people I meet in my travels.
Below are a few of the ambigrams i made (there are many more for which I have no documentation).
Reads "Zenith" both ways.
Reads "Dharma" both ways.
Reads "Basil" both ways.
Reads "Emiliano" upright, "Bernardini" upside down.
Reads "Rene Ekeheien" both ways.
Reads "Tor" upright, "Sten" upside down (forms the name "Torsten".
Reads "James Field" both ways.
Reads "Xing" upright, "Eric" upside down (a gift for a couple).
Reads "Maxwell Fein" both ways.
