Please help me find this great picture of electrical arcs. I saw this photo a while back. I'm pretty sure it was in a magazine. It was of a great big round room, with some sort of large apparatus, like a collider or something (it wasn't a collider I don't think). There were scaffolding and cat walks running everywhere. Lots of pipes and fittings. Everything was gold or copper or something. And the entire room is covered in arcs of electricity. Great big bolts running all around the room, with smaller and smaller branches and fingers breaking off to fill up every metal surface area with arcs. It was some sort of electrical discharge as a result of the experiment that was being run. I can't remember what it was, so I don't even know what to look for in Google. Any help would be appreciated. Even just a guess as to what the device was that would produce that, so I have a starting point to try and find it. Thanks.
