Continuing my pixel bending experiments, this shader converts an image/video into coloured dots, creating a 'retro' feeling (or whatever emotions are stirred in you by the presence of a dotted grid). I tried to get a video demo, but since I have no idea how to do that in Flash, all I got you is this image preview 
. This shader is compatible with Flash.
Parameters
- radius
- Dot radius (in actuality used as diameter
) - padding
- Fraction of the circle radius used as padding between the dots
- snap_to_pixels (boolean)
- Determines if dots are to be snapped to whole pixels. Use this when anti-alias is off to produce better-looking results.
- anti_alias (boolean)
- Makes dots look smoother. Turn this off to produce blockier, more pixelated dots, which look better with smaller radii.
Evil Rabbit!
To get an evil-looking rabbit, pull the padding to 0, reduce radius size to about a fifth of the whole slider, and check both options. Rawr!

Was looking for something like this to use with webcam so that it is not obvious to the user what the subject is but still retains the movement for effect.
If you email me a .zip of all of the source files (.fla, .pbk, video, etc) and code it to work with a streaming video and email it back to you.
ooh, that hair is so cute) even in that pizel shape
