"Painting" an image
This is mostly for Photoshop 3 users or Photoshop 4 users who hate the painting filters that come with the program. First, start out with an image, in this case, I chose an image of my arch-nemesis Weenieman (aka Bill Gates).

Now, just select all and apply the Median filter. I would recommend a radius of 1 or 2, but it really depends on what it is that you're painting. The painted image of Satan Bill Gates is at right.



Here is the painted image of Weenieman. Note the thick glasses, which cen shoot dorkiness rays and are the source of his evil powers.
