We've just been taking a look at artist & cultural activitst Martin Firrell's website, and it's rather lovely.
He works principally with projected text, and has created site specific pieces for the National Gallery, the Tate Britain and the Royal Opera House. He also created the Complete Hero project, which has been screened at Curzon cinemas.
His next project The Question Mark Inside will be a series of projections onto St Paul's Cathedral in November 2008, to celebrate the 300th anniversary of the topping out of Christopher Wren's masterpiece. The projections will go onto the Cathedral Dome, the Ludgate Hill elevation and inside on the wall of the Whispering Gallery.
If you fancy getting involved, you can participate by adding your own thoughts on the meaning of life, and the meaning of St Paul's, at the project blog.
