The entire focus of FlipScript.com is to allow you to create a custom ambigram. You can create an ambigram of any two words you wish. The 'Custom' ambigram to the left is an example of what the ambigram creator can do.
To make your own custom ambigrams,
just 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 custom ambigram.
