where I show how a similar effect can be obtained using Gimp with the newsprint filter.

Or a nicer dither can be obtained by using the attached gimp script (greyscale dither) that I wrote, along with a suitable woodcut dither pattern. I've attached two as samples. There are many more dither patterns here where I found the technique.
The scriptshows up in the menus as Filters->Distorts->Greyscale Dither.
It only works on RGB images. The cleanest results can be obtained by first scaling up the B&W layer to be dithered, then scaling it back down again. (It is optimized to produce a pure B&W image in the default mode. The greyscale modes are a bit of an experiment and aren't true to the dithering technique).
Lastly, I attached the result of running this script on the provided S. John Ross sample, scaling it up 200%, using the woodcut 100 as a dither pattern, then scaling it back down by 50%.

Three cheers for RobA!
Hip hip, horray!

Thank you, that's all very helpful. I still can't figure out haw to get that initial fade-to-white coastline, however.
