I love paintings but don't have the patience or the time to properly learn how to apply paints to my photos.  I may someday.  I've been playing around with some software to get some cool watercolour effects.  (One oil in there as well.)  They are not paintings but it is fun nonetheless.  And with some software I found to add mattes and frames, I can get an idea what these would look like up on a wall.

Below I've listed a couple of apps and the software I've been using.
