I'm actually toying with the idea of making a Farscape T-Shirt and I can't decide on THAT, so who am I to give advice?
Here are some of the ideas I was toying with -
Anything to do with Winnona - be it a sentence or a picture of Winnona herself (not an "it"
) it's a classic, I think
PK symbol, alone or with a text like "You could be more"
Chiana - practically anything to do with her, a sentence, her face, or even a full portrait of her (but on a small scale, obviously...
) The way she stands is quite distinctly hers, you can recognize her from miles.
Zhaan in prayer, possibly with some sort of text regarding the goddess
"The stars are your playground"
I think the main question is what do any of these things mean to you? For me, something like a tattoo should be symbolic, so if I consider guns an awful thing, it doesn't matter that Winnona's "different" - she'd still be a gun, and I wouldn't want that on myself for the rest of my life...
I think it is a very personal process exactly for that reason... All I can do is offer you things which I find aesthetically appealing or otherwise meaningful to me. Sorry I can't be of much more help...
