I've filmed a paternoster lift; I've filmed the strange Genoa elevator that sort-of goes sideways. So when I got an email from Thyssenkrupp, an elevator company, saying "come and see our Multi elevator that actually goes sideways", I wasn't going to turn it down. Full disclosure: Thyssenkrupp paid for my travel to Germany, but that's all they did. I'd got in touch with them last year asking to see this when it opened; their PR firm replied, offering to fly me out. They had no editorial control over this, and didn't get to see it before it was uploaded!
