some kind of repeating thingie

I remember a present from my neighbors as a kid...it was some kind
of Gaelic coloring book...crazy stuff like shields and snakes and stuff...very
"Braveheart" kind of stuff...probably some hagis too but I didn't recognize
it at the time...lots of repeating shapes and the images were divided into
quadrants so the pattern would repeat outward...kinda like this...but
with snakes...
