Home and away

We’re going to be in the US for three weeks from today, starting in San Francisco. Posts will be intermittent until 13 January or so but the RSS feed will alert you to our return. If you're frantic about this sort of gap in your life (and we know at least one of you might be) email us and we’ll let you know when we’re back on stream.
As most of you will have guessed the picture above is a model of San Francisco created in jelly.
