That was fascinating, and way over my head in about two or three different ways. I'm only vaguely familiar with GA (and Clifford algebras more specifically), and again only vaguely familiar with QC (at a pop-sci level). But I found this video fairly easy to follow and enjoyable. I don't have any domain-relevant feedback to offer, but I just wanted to share my enjoyment. I look forward to the next update!

That would be fantastic if you could represent entangled qubits with spacetime algebra like that! I know some quantum computing from Michael Nielsen's and Andy Matuschak's mnuemonic medium pieces, and I agree it would be neat to be able to really visualize everything. I'm surprised you can visualize quantum states with the bloch sphere because that throws away all of the phase information. Does that have anything to do with using spacetime algebra to represent entangled qubits?

If that crystal sphere is "a visualization two entangled qubits," what happens with more than two?
Likewise, with your circuit example, you have two inputs and two outputs. In the case where they're entangled, if you know the crystal sphere for one of the outputs, can you tell what the other one will be? Is each output picture a visualization of the same two qubit system, differing from the perspective of the corresponding input?

As I still don’t know much about this topic, would the “shape” of many qubits entangled begin to reflect the problem being modeled?

That's my hope, although I don't really know enough QC either!
