Im going to aldergrove ATC for my work experience however because of security and insurance reasons im only allowed one day
Ah well, ill make the most of that day. Im not sure if ill be allowed a camera that day but from another point ill bring my camera with me on my trial flying lesson and post any pic's that i get. Oh, i think it'll be alot of fun, however i probably will only be making cups of tea and brushing the floor but i think just being there and seeing everything will be cool. 
Due to the nature of teh job you won't be able to do much hands on work but you'll probably spend the day plugged in, listening to and watching the controllers.
I warn you, it can be addictive! I did my work experience about 5 years ago at Aldergrove ATC. Here I am 5 years later as a controller in London

Have fun!
EDIT: Actually, I just noticed your other post in this forum. D'oh!
