yeah that's been pointed out to me before. When I found that out I took a look at it for myself. And my only defense to prove that I do not nor have I ever used wowtattoo's generator is the fact that the ambigrams I made for Daniel were created nearly a year ago. The generator has only been up since the beginning of June
Letters can only fit certain ways and with the old english style Daniel likes, it's easy to make them resemble. Look at the M and A of "Madison".. they're different.
Simply put, the generator has only been up for a few weeks (June 8, 2008) and the ambigrams I've made to this point we're created long ago. Have a look at my old Ambigram thread.. that thread was created a while back
