Yesterday, we had to take heed of all the notices in the street forbidding parking between 6 a.m. and 6 p.m., since they were resurfacing it. Today, one still couldn't officially drive down it, although a few brave vehicles managed to do so (a large beige van drove past our kitchen window at breakfast time. Backwards, like the opening of Smoke Signals). For "brave," read irritating and foolhardy - for one or two left serious treads in the unset black gloop outside our front door, offering up some examples of unintended abstraction. My catalogue for the wonderful exhibition that I saw at the Whitechapel Gallery ten days ago, Adventures of the Black Square, arrived today, and this is very much in the spirit of one of its sections: the abstraction to be found within the ordinary.
