As the YouTuber explains, the stained glass windows are laminated together with an adhesive, and he's even fashioned several versions to compensate for every set design over the years. His replica of the iron throne is incredibly realistic as well, as it looks like a miniature version scaled-down by magic. A software developer by trade, Omori planned out the entire project in Lego's digital designer program before he started using physical pieces. He tells Thrillist in an email: "Game of Thrones is great to me because there's such an impressive attention to detail from everything from set design to costumes. My recreation wouldn't have been possible without the elaborate and consistently produced work from the people behind the show over all these seasons."
Like the truest Game of Thrones stan on the internet, he recreates an epic scene from season 1, proving that with a little ingenuity and technical discipline, there's no limit to what legos can do, at least when it comes to fantasy programs on HBO.
