Metal Spectrograph

Math ideas:

• update quad lattice generator to just reference triangles?
• random quad lattice generator (or from triangle) where a random set of vertices from within original surfaces is triangluted
  • triangles can either overlap or can share vertices, but probably cooler with shared vertices
  • algorithm to identify the closest vertices on the mesh
    • maybe that one algorithm, the one with the circles and parabolas and whatnot
    • and can that algorithm be extended to 3D by using spheres?
• coordinate systems for various topological surfaces or whatever: torus, concave shapes.
  • properties of these mappings of 2D/3D surface coordinates to 3D
• spiral coordinate system? theta = angle in radians, r = orthogonal distance from spiral
• polygon tesselation oriented towards a central point or using the curvature of the polygon
• spherical indexing for points (grids of spheres of various sizes)
• distort perspective of multiple objects using audio (and groups of objects)
