I made some videos testing out some of the customer shaders. The storybook and the cell shaders are the most fun ones.

I'd really like it if there is a shader out there which offers bigger contrast though, or for the storybook shader to stay consistent, rather then modifying itself depending on how light or dark the scene is. Eihander is a completly different game with the storybook II shader, and would be amazing with a modified shader.
