I recently got a pebble watch, and came across this amazing plugin when trying to make a custom watchface. I needed to dither an image, and this seemed to almost be able to do it.
I edited the plugin with the Pebble Time palette, and figured it would be worth posting here.
I've included the edited source, the icon, the palette text file I made, and the compiled plugin.

Hopefully this is useful for someone!
