THREE IDEAS

1) get the list of the performers who's  performing on the actual day and get their images....use their images to make photo mosaic of all the performers who's performing...

2) take pictures of something which represents sheffield city and put them together to make photo mosaic...

3) collect photos of people of sheffield and i could do this by talking to people one two one and ask them if i could take their picture and used those picture to make photo mosaic because most of the sheffield people will come to the ALIGHT event...

i think all these three ideas could work...photo mosaic could be used as background while the performers are performing on the stage...i could have one photo mosaic for each ( performers/people/place )

or

i could put all the images and use them to make one photo mosaic...
