This week the future (of the world, not Britney again) feels horribly tenuous. Which is why we should live for the moment (or at least the weekend) and celebrate the 25th edition of City Slicker's 'Week's Action, Weekend Reaction'.
1) Incensed with rage over the determined military build-up and unjust war against Iraq when it is actually Al-Qaeda we are after? React by heading to the National Demonstration: No Trident/Bring the Troops Home. Because isn't silence acceptance? Assemble @ Speakers Corner, 12 Noon. Rally in Trafalgar Square 2:30PM. Saturday
2) Always fancied checking out the Barbican but needed a reason? React by indulging in its 25th birthday celebratory programme with an exhibit on Finland's master modernist architect Alvar Aalto or a show by Ireland's Fabulous Beast Dance Theatre. Worth the trip to Moorgate. Runs until 13 May and 3 March, respectively.
3) Secretly pining for a try at Wii with news of their market power? React by catching the last weekend of the Game On exhibit at the Science Museum. For a small fee you get to play 120 classic and modern games for as long as you like, including Space Invaders and Pacman. Who knows when you will get another chance? Until Sunday. £8.50.
