You might have heard about Knitta, a "tag crew of knitters, bombing the inner city with vibrant, stitched works of art, wrapped around everything from beer bottles on easy nights to public monuments and utility poles on more ambitious outings".
Masquerade is doing the same thing in Stockholm, Sweden (which happens to be where I live). I haven't spotted any of these yarn tags yet, but will make sure to go knit graffiti hunting now. They've even put up a convenient Masquerade tourist map.
Seen above is "The Ring" from Munkbrokajen.

I guess stuff like this is what people do in a socialized society where they are taxed like mad for earning money and the government takes care of all their "needs". The good side is that the "grafitti" is easy to remove and pitch when it gets nasty. Wacky stuff (and neat!)
That is my aim!
I'm hoping to get some others in on it though, even if they're not particulaly knitty people. They can still stick them up!
