Hi. I am curious how to make a shader kind of like the one Notch used in Shambles (shambles.notch.net). Please, if you could point me in the right direction or give me some tips. I have no experience with shaders.
Here is a picture of the shader. It “pixelates” the game, probably easiest to see in the road. I can post more pictures, but I did link the game above.

This looks like a detail texture in screenspace(scroll down)
Also the actual resolution of this picture is 468x280. It’s size got doubled afterwards. Something like this can easily be done if you have Unity pro and simply use a rendertexture with a lower resolution and stretch it over the actual screen.
