I found this really cool plugin called pixel bender that you can download for free from Adobes homepage.
With it you can apply a lot of different filters. The most interesting seems to be the one called oil painting. It turns your picture into an oil painting. I attached a file where I applied it to my Drakonia map so you can get the idea. It seems to be a very useful for certain effects on maps.
Anyone else that has tried it out?
