, I think that all the images were taken of the same display on July 7th 2004? I know that Dave's image was taken on the same night from Limerick as my panoamma image further down the page, (maybe Keith and Albert could confirm?)
But from the images it is easy to see the difference that location and time makes. My images were taken at 23:30BST and the displat was all but gone by 0:15BST.
