In the past this column has been a tad lukewarm about the virtual world, Second Life (SL). There is that stuff regularly hauled out for inspection by journalists scraping the story barrel, about virtual naughtinesses and how exciting that is. But Second Life's blocky graphics structure and lack of interesting things to do have failed to impress. Now however at the Serpentine Gallery you can see Chinese artist, Cao Fei, and her RMB City, an experimental art community on an island in SL. You have to join Second Life for your avatar to actually surf it, but the ten or so minutes involved looks very worth while. The less adventurous might take a look at the Serpentine Gallery where they can see a few movies and an aerial view. Quality isn't all that great – presumably because she is flogging beautifully precise prints at £75.
