To the left you will see a Tattoo ambigram. It's an ambigram that says 'Tattoo' when right side up, and 'Tattoo' when upside down. On this site, you can create an ambigram of any two words you wish.
Also, check out this cool ambigram t-shirt and this easily rotated ambigram ring. It's great to sport your ambigram message without the lifetime commitment of an ambigram tattoo.
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...
