XnSoft XnSketch Portable (32/64-bit) 1.18

"Overall, XnSketch does a pretty good job and should be suited for a wide range of users. If you just want the ease and simplicity of one click effects, then this is available for you. ... On the downside, if you do spend the time finessing your settings, there's no option to save your settings so that you can reuse them on other images." —Ian Pullen, graphicsSoft.about.com

XnSketch allows you to turn your photos into cartoon or sketch images.

Notes (included in the help.htm):
» You might need to install Microsoft Visual C++ 2008 Redistributable Package (x64) for the 64-bit version. But try to run it first, if it's OK then you don't need to.[]
