Knitta are a group of urban taggers with a difference. Instead of spraypainting their initials, they wrap the world in wool, a bit at a time. They knit cosies for door handles, antenna, rocks, lamps, signs… anything they can tag with wool.

That afternoon, they knit their first doorknob cozy. Then it dawned on them… 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. With a mix of clandestine moves and gangsta rap — Knitta was born!

The Knitta Crew consists of ten ‘ladies’ (including one male lady), with fabulous names – PolyCotN, LoopDogg and P-Knitty, for example, tagging around the world. They’ve even tagged a stone in the Great Wall of China.

I guess this should be fairly obvious – the CCD sensor in a digital camera isn’t perfect, and they’ll all produce slightly different noise in the images they take. So, it’s possible to work backwards from the image to find out which camera took it. I don’t suppose it even means anything to most of us – it would take a fair bit of doing to match an image back, so the only way it’s likely to be worth doing is for police forensic testing, and I can’t think of any situation off-hand where they might need to prove that a certain camera took a particular picture.

Still, it’s kind of interesting that someone’s actually managed to do it.
