Perceptual Shift ambigram is a design with no symmetry but can be read as either of two different words depending on how the curves of the letters are interpreted.For example, the words “DAD”, “NOON” and “ANNA” form natural rotational ambigrams. Natural ambigram is a word that possesses one or more of the above symmetries when written in its natural state, requiring no typographic styling.Ambigrams that form different words when viewed in the mirror are known as glass door ambigrams, because they can be printed on a glass door to be read differently when entering or exiting. Mirror-image ambigram is a design that can be read when reflected in a mirror, usually as the same word or phrase both ways.Fractal ambigram is a version of space-filling ambigrams where the tiled word branches from itself and then shrinks in a self-similar manner, forming a fractal.Figure-ground ambigram is a design in which the spaces between the letters of one word from another word.Dihedral ambigram is a usual mirror-image ambigram consisting of numerical digits.

Sometimes chain ambigrams are presented in the form of a circle. Letters are usually overlapped meaning that a word will start partway through another word.

Chain Ambigram is a design where words are interlinked, forming a repeating chain.

Such designs can be generated using constructive solid geometry.

3-Dimensional ambigram is a design where an object with different letters will look like of appear to read several letters or words when viewed from different angle.

Ambigrams usually fall into one of several categories: In design, some ambigrams highlight a relationship between their form and their content. Like any other art, ambigrams also hold value for their different meaning and representation under different form.

The way an ambigram is used determines the orientation, complexity and readability. It is an art form or other symbolic representation of a word whose elements retain their meaning when viewed or interpreted from a different direction, perspective, or orientation.

An ambigram is a typographical technique that uses written words that can be read from multiple viewpoints, while sending similar or completely different message.
