Creating a lawn on a sheet of rock

Dumfries isn't thriving any better these days, and they've built the world's ugliest hospital as an incentive to us all to stay healthy.

For anything half-complicated I use Gimp (not very well) and, for simple lines and arrows, I use the editor in Preview - one of the benefits of using a Mac. I'm glad you found it interesting - I'll update it when I get round to doing something. Probably this spring.
