Inverted Light looks the best IMO. Ironically, inverted Darkness looks like crap (or rotten milk) to me. So much for my favorite element...
Can I use the Gravity as my avatar if I give credit?
Anyone can invert a picture within 5 seconds, so you don't have to give him credit.
I'm thinking of getting one as my own avatar too, but I don't know if that is allowed. I have read somewhere only master are allowed to have elemental signs as their avatar.
But, those are inverted signs, so I think SG won't mind that much.
Where did you hear that? That's completely idiotic and makes no sense at all.
