Seirpinski’s Spear

It’s time for a fractal again. I’m calling this one Seirpinski’s Spear. Partly because it is based on the archetypal fractal, the "Seirpinski Triangle", and partly because I thought the final shape was very spear-like - deep, eh? ;-)

Oh, all right, I’m feeling particularly fractal today so here’s one from a few days ago: I called this one “String theory”.
