Vector pixelation filters ?

[morphonius_821]

Just wondering if such a plug-in exists or any plug-in that produces a vector representation of pixelation by employing allot of random little blobs?

Some Background:
After manually tracing a few raster images for projects i found my self putting in allot of detail and re-creating allot of the stray pixels to recreate the raster feel with my vector design....
(shown bellow
But anyway i wondered if there was some kind of plug-in that could produce a similar effect... as it is an approach I'm fond of but im not fond of spending a month of sundays digitizing every little blob....(like im currently doing for a few pieces I'm working on...

i think a plug-in to reproduce randomized small blobs would be awesome...
ideally i would like this plugin to have features simillar to the functionality that already exists in xara for blurring, feathering and blending....
ie instead of the smooth blends evident in all these examples in xara... this plugin would have the same functions but instead of smooth colour transitions the blend would be done by changing the density and size of small blobs... to imitate the manual pixelation effect i have demonstrated...below...

ie you could have a feather function which would put dotty fringes around objects... a blur function which would fill the shape with a dotty effect increasing in density towards the middle and you could also alter the density and size of the blobs with effects like linear and elliptical fill effects ie..except instead of controlling a colour transition these would control the density of the randomized blobs....

you could also have settings for min and max blob size and a profile for the dispersion of these sizes....
a random factor perhaps
and also perhaps a roughness factor to control the type of shapes it would produce ETC....

So anyway you could use such a plugin as this to recreate the blobby blending effect shown in this manual trace design....
just dreaming i guess......i would love this...(i dont suppose such a plug-in or anything like it already exists?)
