I recently found a cool way of modifying images recently. A little android app which applies filters to images. It's called Pencil Sketch (although I'm sure there are others out there). I just thought I'd share some Trainz screenshots I've created using it (is there any better way to test it than with trainz screenshots ;-) )
Feel free to post any modified screenshots of your own and include what you used in case others want to try their hand at it too.
