If you were a fly on my ceiling last night, this is the view you would have had:

The spring winds gusted in last night and something or other, which had been left there by someone or other, banged, at irregular but frequent intervals, against something or other else. Of course, now that the sun is up there seems to be no sign of it.

(I drew this on my ipad using the brushes application. I, along with zillions of others, bought brushes after watching this video of a New Yorker artist creating something on his iphone. Apparently, it takes more than a piece of software to turn you into an artist.)
