been censored and arrested, such as Jamal Khashoggi. The neoclassical virtual building was created over about 250 hours by an international team of 24 people. Despite its unpredictable nature, Minecraft has become a popular game for speedrunning, where players time themselves from being dropped into a new world to reaching The End and defeating the Ender Dragon boss. Some the speedrunners use a combination of mods, external programs, and debug menus, while other runners play the game in a more vanilla or more consistency-oriented way. Education Minecraft has also been used in educational settings. In 2011, an educational organization named MinecraftEdu was formed with the goal of introducing Minecraft into schools. The group works with Mojang to make the game affordable and accessible to schools. The version of Minecraft through MinecraftEdu includes unique features to allow teachers to monitor the students' progress within the virtual world, such as receiving screenshots from students to show completion of a lesson. In September 2012, MinecraftEdu said that approximately 250,000 students around the world have access to Minecraft through the company. A wide variety of educational activities involving the game have been developed to teach students various subjects, including history, language arts and science. For an example, one teacher built a world consisting of various historical landmarks for students to learn and explore. Another teacher created a large-scale representation of an animal cell within Minecraft that student could explore and learn how the cell functions work. Great Ormond Street Hospital has been recreated in Minecraft, and it proposed that patients can use it to virtually explore the hospital before they actually visit. Minecraft may also prove as an innovation in Computer Aided Design (CAD). Minecraft offers an outlet of collaboration in design and could have an impact on the industry. With the introduction of redstone blocks to represent electrical circuits, users have been able to build functional virtual computers within Minecraft. Such virtual creations include a working hard drive, an 8-bit virtual computer, and even a smaller-scale version of Minecraft that is playable and able to be built completely in survival mode with no external modifications. In at least one instance, a mod has been created to use this feature to teach younger players how to program within a language set by the virtual computer within a Minecraft world. Another computational mechanic in Minecraft is the command block, a block that is only accessible
