BarCampSheffield's on today and tomorrow. I've been working with PlusNet, the organiser, in the run-up, and am gutted I couldn't be there, but it's just a bit too far. I was up at Internet House Sheffield earlier in the week though and the set-up's all spot on.
Have a look at the webcams in Internet House to have a gander at what's going on. PlusNet has also rigged up groups on Flickr for pics (already 191 up there), Blip.tv for vids, they're linking to buzz on Technorati, Google and del.icio.us. They've got some people feeding some cool content to these sites too.
