This spiral here shall show you, why I need to get a social life. I have so much time on my hands that I can create this massive spiral. It goes up to the height limit. I am not sure what the height limit, can’t remember. Will have to check. Spent about 3 days on this, since I am working on another minecraft project and free building on a friend’s lan minecraft world. Edit: Just checked, the light beam from the beacon ends at approx 314 blocks high.
