I want to write a shader/filer probably in adobe Pixel Bender that will do the best job possible in emulating the fill of an oldskul monochromatic arcade CRT screen. Much like this here:

Here are some attributes I know will exist in this filter:

1. It will take in a low res image 160 x 120 and return a medium res image 640 x 480.
2. It will add scanlines
3. It will blur the color channels to create that color bleeding effect
4. It will distort the shape of the image from a perfect rectangle into a rounder shape.

The question is, could you please provide any other attributes that are beneficial to emulating an arcade CRT feel and links and resources on coding these effects.

Thanks
