I have a paper on pattern formation in the March/April issue of Architectural Design, a special issue devoted to ‘material computation’. My piece is fairly old stuff, I confess, although this is a topic that architects are becoming increasingly interested in. I will put a version on my website, once I have figured out why it seems to have (temporarily?) vanished from the webosphere. But there’s a lot of other interesting stuff in this issue, some of which I have written about in my next column (May) for Nature Materials.
