The whole idea behind my previous project (http://www.planetminecraft.com/project/impossible-nether-portal/) was; your in the overworld and then there is a see through nether portal! After posting it i realised that my project was kinda strange, so i decided to post this to explain what the heck my project is! I hope you now understand the idea behind the project and that you will have fun with the world! Have a nice day!
