Your voxel ambigram is cool! The first view(道?) seems a little busy, but 2nd and 3rd views (江湖) can be clearly recognized for me. Wow, you are playing Chinese font!
As you mentioned, the theorem related the 3 orthogonal projection. If we project 2 faces on 3D cubic, it certainly can be done. But if we project all three faces, some 2D shapes will conflict on certain volume. For me, it’s better to use one-piece of connected 2D shape instead of several separated region. Chinese single-words are usually with a complicated shape than English letter. Good job.
