This is a set of celtic avatars I did recently. This is more or less my end of year present to deviants. :] The zip file contains the 8 different images.
You are FREE to use them within deviantArt (well, if you want to give me points, that's welcomed )
If you wish, you can also add a line in your signature/journal saying "avatar from ..." + the url to here, but that's not compulsory, just do as you wish.
About the knotworks: - Knot 1 is a "personal" design, meaning I didn't look at any reference to do it, but it's so simple that I think everyone drew it once. - Knot 2 is based on a design from the Book of Durrow, referenced from George Bain's "Celtic Art - The methods of construction" book. - Knot 3 is based on a design from the Monymusk reliquary, referenced from the same book as above. - Knot 4 is also a personal design. I tried to link in a single line two figure-eight knots.
BTW, I know menhirs are not really from the same civilisation as the one that did the knotworks, but I wanted to add one anyway I did the triskels with the swirls that "touch" the other, so I could make it look like clover leaves. The "dA colours" version is for people that like discreet avatars.
Everything above was done with Inkscape and GIMP. I tried my best to make the knots "legible" even in 50*50px.
