Still a work in progress but here is the Enchantment Tower build for my custom SMP server ChoofMC.
I wanted to try using the newer blocks for this build, so I used warped blocks and blackstone. This tower will be located in spawn as a "Public Enchantment" area for my server.
If you guys want to hop on and play, the server info is:
