this website has it down as 24th July - 6th August

here's an article i found on the event

strangely i can't find a website for the event itself
the event seems to be well publicised by the media but the lack of it's own visible website makes it hard for people to find out what exactly's going on 
wouldn't even know how to buy a ticket for it
