Hemant mentioned that he wanted a "flying spaghetti monster" ambigram tattoo.
That struck me as a pretty tricky thing to do, so I had a go at just making "Spaghetti Monster" just to see if it was possible. It's a quick and dirty attempt with no artistic merit, but I think it's adequate as a proof-of-concept that an ambigram something like what he wants should be quite doable in the hands of a more accomplished artist with the time to attempt it.
The Atheist "A" was just something I tossed in at the last moment (I noticed it on my blog as I was about to upload a first attempt and wondered if I could work it in. The answer was "yeah, sort of").
