Ooh, that's lovely.
Paint by DS is a 'digital colouring book' in which you're able to splash paint all over classic paintings by artists such as Van Gogh and Cezanne. Mix your own water or oil paints, or use coloured pencils, and go for it. We're not sure if you're absolutely have to try to re-create the original, or if you can, say, produce a lovely hot pink Van Gogh. While this seems to be less of an actual game and more of an idle distraction, there's something seductive about the idea. It doesn't all have to be about saving the world/galaxy/princess, does it?
Paint by DS is due this December.
