Random London Fact of the Day
The RAC Club on Pall Mall contains many peculiar objects and stories. Its statue of Queen Victoria was unveiled by Kaiser Wilhelm II, whom we later went to war with. A rather splendid meal, eaten in reverse order, was held there in 1913 to mark the occasion of the first aerial loop-the-loop. And the famous spies Burgess and Maclean ate their last meals here before defecting to Moscow. All this we gleaned from the most excellent London Hidden Interiors.

Good Cause of the Day
Party for charity. This Friday, Stitch Project (celebrating its second birthday) is hosting a night of live music and DJs at Red Gallery in Shoreditch. What sets it apart from the countless other DJ events on a Friday night is that proceeds from the door and bar will go towards funding a reforestation project in Ethiopia, run by charity WeForest. They hope to raise enough from this one party to plant 10,000 trees. Get your tix here for less than a tenner.

London Weather
Despite being 50 million miles further from the sun, even the fricking surface of Mars is more pleasant than London right now. You can almost sense the smugness from NASA's Curiosity rover, currently living it up in Gale Crater with balmy daytime highs of 3ºC (London may reach 2ºC) and wind speeds of only 4.5mph (London 14mph). Curiosity enjoys similar daylight hours to us, but with only the most wispy of clouds. If you can find a way to breathe tenuous concentrations of carbon dioxide, then might we suggest, in the sage words of Arnold Schwarzenegger, that you "get your ass to Mars".
