Sorry for the long title but I’m wondering if there is a title for the art where an artist comes up with a word that says one thing when facing a certain direction and it says something else entirely when facing the other direction. The common examples being “Hello” and “Goodbye” or there was a shirt that said “Love” regularly and “Hate” in a mirror.
‘Ambigrams’ is the term coined to describe the work of genius graphic artist Scott Kim. He didn’t invent letterforms that can be interpreted in different ways - they have been around almost as long as letters - but he did so much to break new ground and achieve new effects that his name has become synonymous with this kind of visual wordplay.
To find out more, Google or search on ‘ambigram’ and ‘Scott Kim’. And buy his book, ‘Inversions’, which is utterly absorbing.
