This is MCT64D — meaning concept trajectory · 64d. We built it to depict higher-dimensional concept space: the raw relational geometry underneath an LLM, before the extra machinery gets baked on top. An embedding model read real books from typically isolated — yet quietly similar — domains: the KJV Bible, the Tao Te Ching, Eddington’s quantum physics, William James’s psychology. We didn’t author where anything sits. The space is dynamically relative: every concept holds a position in 64 dimensions, projected down into this 3-d hyperspace as you approach and retracted back out as you pass.
Add an mp3 and the soundwaves become orthogonal wind — blowing related concepts down into 3-d space and scattering distant, unrelated ones back to the adjacent dimensional planes. Add a lyric-timing json and you can ride the song through a curated concept space. You are the RD Wolf: drag to steer, strike words, carve. Press m for everything else.
Honesty note: this isn’t perfect. 256-dimensional embeddings (Voyage) are reduced to 64 with a PCA fitted on the union of the books; where older spaces had to be melded, a Procrustes rotation kept concepts in their semantic clusters. It could be better — this is just v0.1z41.
