To the left you will see a Tattoos ambigram. It's a symmetric ambigram that says 'Tattoos' when right side up, and still says 'Tattoos' when upside down. On this site, you can create an ambigram of any two words you wish.
Feel free to check out this cool ambigram ring and this ambigram t-shirt, which still have cool ambigrams, but without the lifetime commitment that comes with ambigram tattoos.
To make your own ambigram, click the button on the top of this page that says 'Create New Ambigram', and type in the two words you'd like to have in your ambigram...
