A brane (short for membrane) :== some mathematical generalization of a category from zero (0) or more higher dimensions. A combination of branes is called a mesh.
My portfolio is a twenty-six dimensional (26-dim) toy [🧩puzzleware] with braneworld structure according to pitch class:
0-brane = point particle
1-brane = string
2-brane = manifold/sheet/tape
3-brane = cell
25-brane = Starbureiy automaton
