guess I need to reference games that my examples of pixel art / 3D models I'm using are from:
- proposal has Space Invaders and Zelda 1/LttP/Minish Cap
- standard test models are Stanford dragon/Utah teapot
- current Pokémon model used in shader is from PokéPark 2, and the corresponding pixel art is from Pokémon Black/White
- add more to this list as I use them
