Here's a suggestion for your file, from a conversation tonight with china_shop:

A paint challenge -- painting, painters, paintings, watercolors, acrylics, oils, tempera, fingerpaint, modelpaint, housepaint, consulate-paint, six-coats-of-black-enamel-on-the-GTO-paint, any kind of paint.

I'd also include fingernail polish, face paint (Due South needs more mimes!), Frannie's art class, and Turnbull's portrait of the Queen. :D
