A new daily post, highlighting the best things to do around town today (that aren't fully booked). We welcome additions in the comments.
- WEAR RED: Today is Wear Red Day, in support of London's Air Ambulance. Don that crimson skirt, scarlet lipstick or cardinal's robes (or maybe just a tie), and donate at least £1 to this important charity.
- FREE MUSIC: City Showcase, a cross-London festival of new music, runs 9-13 October, but today's your last chance to register for a wristband to get into certain gigs for free.
- CANNIBALISM IS FUN: If you've ever wanted to dig your teeth into a human face without incurring a custodial sentence, head to Smithfield Market where a pop-up butcher is offering edible (but fake) human body parts for sale. 9am-6pm
- FREE FOOD: The Royal Albert china company serves up free tea, macaroons and cakes from a van in Fitzroy Square. You're also encouraged to dress up in quintessentially British garb. Free, just turn up 11am-5pm

Random Fact Of The Day
Have you ever spotted this simple graffito around town? It's the work of Turner Prize-winner Mark Wallinger, who you might also remember from his Fourth Plinth piece Ecce homo, and his recreation of Brian Haw's protest. In 2010, Wallinger scrawled his first (and appropriate) name onto dozens of walls around town. Many of the Mark marks still remain, especially in Soho. Where have you spotted them?
All you need to know is that is should be both warm enough and dry enough to stand outside for your Friday night beers.
