An inversion, as defined by Scott Kim, "is a word or name written so it reads in more than one way." A strict example would be a word that is calligraphed in such a way that it reads the same whether right-side-up or upside-down. But it is also possible to design inversions that read as one word right-side-up and a different word upside-down; or as the same word whether mirrored or not; or the same word readable in multiple directions (the Sun logo could be considered an example of this). There are a limitless number of variations on the theme. Visit Scott Kim's "Inversions" page on the Web at for more examples.
