Sunday 13th - any ideas?

Urban beach was suggested, but as Stephen pointed out it may not offer all that much grist for the 'creative' mill (of our artistic genius!). Anyway, enough appalling metaphors... Does anyone else have any ideas for indoor or outdoor locations they'd like to try out? There was talk of St. Audoens last week, or the grounds of Christchurch or St. Patricks cathedral. The Chester Beatty also has a couple of nice exhibitions and a roof-top garden which could allow for some interesting roof-scapes. Dublin castle itself is quite interesting now that i think of it... just post your preference here please. :-)
