I think the IPU symbol has been mentioned by somebody. The symbol I would choose should promote intelligent discussion and this one works for me. Here's a link to some tattoo images of it.
I have the IPU car logo and people are always wondering what it is which gets into some funny conversations where I don't even mention the word 'Atheist'. I think it looks very cool as a tattoo all on it's own regardless of meaning too. Better than all the symbols with the letter 'A' in it somewhere (like a scarlet letter or something).
I know this is a late arrival, but I've been thinking of using Spinoza's Caute! sub rosa. I feel it would be a good reminder that, as atheists, we shouldn't have to hide our beliefs. Of course, I would leave Spinoza's initials out of it. I would consider inserting my own.
SICK BRO ! Actually pretty tight wording too makes sense - i just got ATHEOS going down my tricep
nice, Post a pic!
I am also looking or an appropriate tattoo image that speaks to me. I found this one that I like and am considering getting it on my foot. I like the organic look it has over other typical atheist A symbols.
Hmm I like the electron orbit better in that one, but I also really liked the red A.
There's no saying you can't combine the two. The 2nd one has more depth to the line thickness and the interweaving makes more sense.
Wow Mark, these are stunning! I have a couple of tatts, both are symbols of the love I carry - one for a woman who died, one for a woman who survived.
I am seriously interested in possibly using one of your above drawn pictures - do you feel possessive about them or are you sharing freely?
The above symbol(s) have been tattooed dozens and dozens of times already, even by members here. I can no longer control it, so have at it. Just don't make money from it. ;)
