November is a month when creative people of all types set themselves all kinds of challenges, like NaNoWriMo (the National Novel Writing Month) and its junior equivalent PiBoIdMo (the Picture Book Idea Month). For artists, there’s also SkADAMo (Sketch A Day A Month), in which the challenge is to post … well, it’s self-explanatory, really. My favorite participation has been that of cartoonist Martin Hand, who’s been posting charmingly crude, Panter-esque, comic swipes paired with unlikely but always fitting quotes from literature, advertising and music. I was almost crying with laughter when I saw that Ulik the troll/R Kelly mash-up above turn up in his Twitter feed. There’s a lot more below.
