Sample Tile Set for Homebrew Sorter
I'm thinking about a white or yellow outlined square in the middle for Demo, not sure how to pull it off yet.
NOTES: It might even be easier to only have the grid with five colored squares, and place the color in the grid in the proper location. Or for single catagory let one color fill the entire grid, and only start with small blocks when more than one catagory is selected.
These are in gallery mode with desctiptions.
