Excited by a new knitting technique

I find it wonderful the many ways arty people come up with new ideas and techniques to create and make art.  Ardrtiafil is a Italian company that makes beautiful yarn and has apparently come up with this technique for knitting with your arms. I find this facinating as a whole wrap or scarf can be completed in an evening with the use of Ardrtiafil's chunky yarn. Here your arms act like knitting needles and you cast on and knit from one arm to another.This video shows you how

It is really quite interesting to watch. The only thing is I cannot get that yarn here in New Zealand and am wondering if any other yarns might do the same thing as well...
