I made this a while back on the MCSchematics server out of coble, dirt and saplings, but it grew into much more. I also tended the forest around my tower until it was filled with large trees embedded with glowstone. It was a fun project, but sadly it was lost when the server was erased by the company who owned the comps it was held on. Anyway, I found these old pictures and figured it might inspire someone to build and equally simple yet fun building.
There will be no schematic as it was lost.
