It's one of four layouts that Australian designer Chris Timmins teaches in her Designing with Strips workshop. You could contact her to see if there is a pattern available. (She's the 3 armed lady in the photo.)

And, yes, it's 6 strips according to the workshop description. I believe the pattern name is Take 6, but not positive.
