A new form of graffiti?

actually it is in Stockholm Sweden Tarik ha,ha,ha... but ok ok both Scandanevia and in the notrh of Europe ..... in any case this is an example u see pieces of knitting on lantarnpoles, bridges etc. it is really cool .... so my question is could knitting become the new grafitti..........??? has anybody seen this anywhere else in the world or is this specifically to Stockholm or Sweden?
Curious to hear back form u all !
over and out, Sasha
