Northumberland Rock Art

Here is a fascinating site for a couple of reasons: the content, if you like prehistoric rock art, like I do; and the weirdly difficult-to-use design, which looks at first glance like it should be really usable, but on inspection proves to be so flexible you can barely get anywhere-- at least not without a thousand clicks you don't entirely understand. Or I couldn't, anyway. I finally picked this as a good way to look at the massively tagged contents: Northumberland Rock Art - Browse by Art Motifs -- if you want spirals, here's where you can find them.   

All in all, obviously a labor of love. Points for passion.
