London suggestions?I'm going to be visiting London and Cornwall next month. This is very well worn territory for me, so I'm really going to make a conscious effort to see something new in the capital. Anyone have any suggestions for things in London that are either brand-spankin' new or off the beaten path? Particularly stuff that's design-related. (Unfortunately, I'll be there too early for the Terrence Conran show at the Design Museum.) An account of my last (brief) visit is here.
