We’ve seen lots of ways for an automaker to unveil a new car. They can do it online, at a special event, at an auto show. They can show us sketches and spy shots, they can give us a full array of photos, or they can make it all a big surprise when they pull back the sheet live in person. But this has got to be a new one: Opel has given us our first look at its latest concept car via hologram. @funkmasterflex
