Friendsfeed at livejournal brought me an absolutely delightful online drawing tool called harmony - http://mrdoob.com/projects/harmony/#sketchy
(if server is not working, it's because everybody's passing on this link, just wait for a bit).
I freely admit that I spent unreasonable amount of time drawing things. Shame it doesn't allow to save a hi-res image, but never mind the usefulness, eh
Having a graphic tablet helps, but mouse's good too.
