This is a square/round (as opposed to flat) braid created with doubled strands of fine-gauge wire. It makes an interesting base for sliders or Pandora beads. Click here for the tutorial.
I had this braid sitting on my desk all summer; I'd pick it up and work on it when my computer was busy processing so I don't really know how long it took me to braid. I think it takes less time than Viking Weave, but then again it depends on your proficiency at each.
