This mod for Sethbling's SMW Jailbreak is basically Dotsarecool's "Super Mosaic World" with a few more customization options and can technically be played on a real cartridge! The SNES mosaic effect basically pixellates the screen, making a pixel up to 16 times its original size.

Controls:

Use the L and R shoulder buttons to change the size of the mosaic effect. There is an indicator on the status bar to let you know how big each mosaic "pixel" should be. If you are angery because layer 3 isn't affected by the mosaic just press Select on the second controller to toggle it.

Each change to the mosaic levels takes effect whenever the game fades or something.
