It's actually a screen saver, but you can do a screenshot of it when it's close to being finished (not when it's finished - it goes straight to a new picture).
I've spoken to the owner (it's a freebie) about making it a exe file with save capability (or having the s-saver have a key (F1, eg) to save the image - he's very helpful, so we may get results.
Use the s-saver on 'splat' mode, with small splat size, and you get lovely painterly effects!! http://www.onwijs.com/e_screensaver_vb.html

Get it!! Try it out - it's fun!
