I'm not sure if this really qualifies as "art" or whether this is the place for it.
I saw a pic of the day over on KOTOR Files that looked like it was a screenshot that had been run through some sort of cel shading filter. It intrigued me, so I thought I might have a play with it myself. I used a pic I had to hand from a WIP thread. Not the best source material to work from, but adequate for a quick and dirty test. The first pic is the original, then the three tests with various combos of filters.
The 1st test was a bit of overkill, but I think something halfway between the 2nd and 3rd tests would make a great style for a comic strip. Might be an idea for someone doing short stories that wants to move to something a bit more visual.
