There are 4 bright rainbow marble images in this set which have also been muted to pastel-type versions as well. You'll see them as the Plumbob spins in the beginning, and every time your game loads a lot.
Each loading screen is in its own package, as they override the game's loading screen. In the zip file is a folder. In the folder are the 8 packages and their corresponding image files (png) so you can easily see which screen to install.
