Yesterday, we at Greenpeace UK staged a demonstration at Admiralty Arch in London where refurbishments are currently taking place. We've identified the plywood being used as hoardings around the site as having been illegally logged in Papua New Guinea and this is the third time we've exposed this problem on a government building site - they've even had a procurement policy in place since 2000 so you think they'd have got it right by now.

Fourteen protestors climbed onto the roof of the Arch and one of them had a camera phone while I had one on the ground. During the day we published images and videos direct to the web using moblog.co.uk and even though it was something of an experiment, the results have been pretty impressive. Things learnt include not trying to record vox pops next to central London rush hour traffic (doh!) but I found it an excellent way to tell the story of a protest as it's happening and draw in people who might not otherwise have heard about it.

While we were there, loads of passers-by stopped to take pictures and some have ended up on flickr (flickr search is a bit dicky so you might need to refresh) - it makes me think we should have promoted a shared moblog to those people and encouraged them to share their pics. One guy even came out of one of the offices next to the Arch and Bluetoothed over to me a video clip he'd taken of the climbers going up the building!

We're just starting to develop this kind of stuff for our actions so I'm not sure quite what else of this nature has already been done but if anyone has any ideas or experiences they'd like to share, please do!
