The valknut is an ancient Scandanavian (Viking) symbol composed of three interlocking triangles. The symbol is not recognizable in this tile, even though it structures the overall design.
Here is a Valknut metal pendant:
Even though the Valknut symbol is new to me, I've been a fan of other ancient Scandanavian symbols, the runes, for years. A few weeks ago, I finally took the time to visit the Kensington Runestone Museum in Alexandria, MN, home (to no one's surprise) of the Kensington Runestone. Some people believe that this large stone with runic inscriptions, discovered on a farm in this Minnesota farming town in the late 19th century, is authentic, which would mean that that Vikings made it to the North American continent in the 14th century (1362). The stone has been dismissed as inauthentic, but not everyone agrees that it's a hoax. Whatever the truth, the stone is really cool looking.

After my trip to the museum, I visited some websites devoted to the runes and other Scandanavian symbols. The structure of the valknut was so mind-bending to me that I was moved to spend some time trying to figure out how to draw it in a relatively straightforward way. Here's what I came up with:
I didn't use a different color for each part (sorry), but even so, I think it's fairly easy to see how this goes. If a 9th step were included, the lines left hanging in step 8 would simply continue around each of the three triangles like so:
The colored tile at the start of this post uses step 7 again and again, randomly placed over the tile, with pearls added in the spaces afterwards.
