Free ambigram generators are available at Ambigram.com, Ambigram.Matic.com and FlipScript.com. An ambigram is a design that looks the same when observed from two or more orientations. Many ambigrams are words or phrases lettered in such a way that they look the same when they are rotated 180 degrees.
Simple ambigram designs have been used for many years in brand logos, but ambigrams with words have become popular as tattoo designs and as graphics on T-shirts and sweatshirts.
In addition to the free ambigram generators, one can also use an ambigram generator with more fonts and functions for a small fee, or one can hire a graphic designer or calligrapher who specializes in creating ambigrams.
