Realtime. A look you've never seen – Olli by Tinrocket Review

The developers figured out how to make realtime modifications to images that don't look like the same decades-old edge detection. It's a line art effect with various fills that work better for portraits, still lives, outdoors, etc. The downside is that the current app's output is pretty low res. Don't plan to zoom in or print unless they improve that. It's a nice complement to some of the better new brushwork-type apps.
