Thanks to Moomoney, I got my hand on this really interesting, FREE (yes, legally free) plugin for Vegas (it works with other video editing programs as well).
The plugin is called Cartoonr and you can get it here (registration is required). And here's a video of Cartoonr in action.
What Cartoonr does that it cartoonizes your footage. Quite the same trick which is easily doable on Photoshop.
I just installed it, played with it and here is one test - the first picture is before the filter and the second one after.
I'll test it more with No Point: Stretching Time and maybe consider giving the movie a very interesting look.. we shall see :)
