On Friday evening we went, with Margaret, to see the Lumiere light festival - light-based art installations in various sections of central London, plus up in the new pedestrian area north of King's Cross. We decided to go to King's Cross, and found it to be really busy and also somewhat disappointing. Most of the things were quite small; the biggest thing was an animation projected onto the front of a large building, which if you saw it on TV or Youtube would not have detained you for more than 30 seconds before you turned it off.
I know other people who went and were really impressed, but perhaps they all went to the central London sections. Oh well, at least I visited an area of London I hadn't been to before, not since the redevelopment at least.
