I'm making a comment here. How about a texture/resource pack that focuses on Cubism as well? Like changing the textures to be that of colored cube that would represent what they are? Grass = green, lava = orange, obsidian = purple-ish, etc?
Wouldn't that be a 1x1 resource pack? Unless you mean each texture is a Cubism image by itself, in that case sounds interesting, I might see how it works!
