I recall a young man building a portion of the 'Game Of Thrones' theme video. Think watching a real-life mechanical, clockwork Winterfell or Kings Landing twisting and rising all out of pop-up flatwood in your spare bedroom. I've tried a quick search on Youtube for the video but couldn't easily find it. The kid's friend joked about how soon HBO would hit him up on copyright.
