Slimber is a very simple online drawing tool that requires no registration.

Once you go to the website, you click on “painter” at the top, and you can begin creating. Once you’re finished, you can click “play” and it will “rerun” the artistic process you used. After clicking save, you can write a description of your image. Next, click on “gallery” where you can see your creation and get a url address or embed code.

I’m adding it to The Best Art Websites For Learning English.

Thanks to The Make Use Of blog for the tip.
