VERY compact lighthouse

I just happened to think of a really good way to make a compact lighthouse, this is completely my design and im quite proud of it. The best part is that if the chunk the lighthouse is in get unloaded, the lighthouse will still work when it gets loaded again. Hope you can make use of it and enjoy :)

If you want, please comment on what you want me to build next, ill build almost anything, redstone device, modern building, medieval building, just let me know and ill try my best!
