This is a creative commons project that I am doing. Basically this is a free image that you can use to sketch your ideas, make games prototypes. Well, anything you want. You may even use it in a commercial product. Also you don't need to mention the author (me) but I would be happy if you do it

Well, here's the first image, soon I'll post a lot of "expansions"

If you need the PNG (tranparent background) you can get it here: [link]
