Sorry don't know how to post links. A banner for it was at the bottom of an article by Gina Martin, who campaigned for an upskirting law, on today's (Tues. 8th) Guardian. It's about abuse faced on-line by women and girls. I think tickets are in the region of £7-8 and it's virtual. I've not seen another post about it but sorry again if this is a duplicate.
Her article is interesting, v. inc.
