Last Wednesday when I was in town I happened to walk past Riddarfjärden and see the City Hall across the water, with a spectacular light show. I guessed it was connected to the Nobel week festivities. When I later googled to check, I found out that it was a whole thing, with light installations at at least twenty places around Stockholm. I wish I’d known about this before – I’d have tried to see more of them. The City Hall probably got the most impressive installation, but I’m sure the rest were beautiful and interesting.
