I made this picture in Wesnoth Editor. Is a map editor included in a open source game named "The Battle for Wesnoth". And is one of many other open source projects sponsored by Google.
I want to use this game for a multimedia book for kids. Is great for telling stories. Until then, if you like this picture and want to use as a post card, feel free to use it. Click for zoom and then save it on your HDD.
