One of the many cool details woven throughout the story of Game of Thrones are the sigils for each of the Houses. Each is unique and has their own style and meaning. Fans have reinterpreted them many times and using many mediums over the years. In this case, they are done in LEGO form.
These were created by LEGO fan Omar Ovalle, and they look just awesome. It’s too bad these aren’t official LEGO sets with matching mini-figs included, though they seem simple enough that you could probably make them yourself if you wanted to. It always amazes me what people can do with LEGO.
They are the work of Omar Ovalle and you can see more of his designs on his Flickr page.
