for those curious after tet and I's Team Speak chat, here's the building I'll be constructing:
from a rough (but now superseded) 3D image i made in Blender:
to exporting it and turning it into Voxels:
The bowl at the top i've not decided on material wise, but the twisted legs will just be alternate cobble and stone.
i doubt i'll want to use the building so will donate it to Tetra as a multilevel Spleef Arena
