I'm not one for specialty software for creating art. I use CS6 Illustrator, the master program that allows me to design vector patterns with mathematical precision. And I use Photoshop for a few subtle effects, but mostly for formatting raster files.
It's highly unlikely that I'll ever learn to paint, though. So, I was intrigued from the start with Dynamic Auto Painter for $99 - on sale for $50. After thinking about it 6 months, I bought it.
Gosh, it's fun! There are a lot of painting styles to choose from and countless custom options for tweaking the process. But I just like to pick a style, click play, sit there and watch it paint whatever image I've opened! Be assured this is not like Photoshop filter.
For $50, I got more than my money's worth. Only time will tell if it will be useful to me professionally. (Click on my images to enlarge them.)
Here is a photo of the lake I see from my back door:
Here's what it looks like after I used the Van Gogh Starry style:
Here's a closeup. I started with a high res image and ended up with fantastic detail:
