Well, it's about the maximum safe level of carbon parts per million in the atmosphere, above which the risk of runaway climate change is very very high.
here's some photos of my first craft activism expedition (with thanks to Rozi, Josh and Josh for help!) to get the number visible in the city (briefly). This was actually back in last October, just before the global day of action on climate change- which was Oct 24. 350.org is a fantastic group making links between climate action orgs all over the world- with the aim of getting action based on scientific evidence about what the world needs (ie. 350 ppm) instead of what is politically expedient or the fact that big polluters don't want to have to change their ways.
in blog news I'm just starting to make an effort with updating again now (after being reinspired at Woodford, about both art and activism!)
and here they are in the homes they found around the place, for a very brief life in the limelight, before they were all taken down by maintenance.

I made about 60. my hands were mighty sore from all that crochet!
Oh yeah, and my friend Josh wrote a blog post about this project too (and writes the funniest blog I know in general) where he says nice things about me. He also wrote a book which is faaaantastic and you can read about it on his blog too. yay!
