Part of the experience of being a cartographer is collecting a useful set of textures for the kinds of maps you want to make.
Just a quick note. You can't buy Dundjinni. Make sure you read the Dundjinni forum posts for information regarding the Dundjinni store; which will accept your money but not deliver a key. One might argue that if you paid you have the right to run a copy of Dundjinni. I think someone needs to start up a Dundjinni clone :-)
