Guys,

If you're looking for tools and don't want to spend any cash, this might be worth a look!

"Mission statement: As with most things, it all began with a squirrel, or rather a squirrel and a peacock, but never mind that. Project dogwaffle is a paint program, not an image editor. If you like to create pretty pictures then dogwaffle should do well. Dogwaffle doesn't try to be too much like the other programs - that would be a waste of time. Dogwaffle is also meant to be fun."

It is. Dogwaffle offers some real power and flexibility, and is a serious tool with features that you expect, such as painting on layers with various media, brushes and paper textures. And some features you don't see elsewhere, such as procedural brushes and the capability to use visual basic to write plugins and expand on the application.
It is worth seeing it, take a look at a screenshot and download it for free from here
