Boom - it was at the Barbican this weekend just gone and they were having a 'weekender' event kicking off a programme of events called 'Wonder - Art and Science of the Brain'. Basically there were loads of stalls set up allowing you to (amongst other things) experience a sonic tour of the brain, knit a neuron and listen to a the music of the mind. Just a load of random events, and there's loads more to check out over the coming month or so (including movies, talks and walking tours.
On the last weekend (April 7th) it appears they have another day of events to close the season. See: http://www.barbican.org.uk/wonder/participation/street-fair
If any memebers wish to meetup up and take a mosey round together, or simply fancies meeting up for a coffee whilst there then do RSVP and we'll see what we can sort out!
Finer details to be sorted closer to the time.
