I was in Plainfield, Indiana for a class the other week, and i had gone tothe bookstore in this mall and was amazed at how neat this mall looked. this was during the day when i saw it. i got permission and went back at night and was amazed. the lights kept changing and it was a fascinating place. i had never seen such a light show at a mall. here are some photos that i took from it. most of the exposure times are iso:100 speed: 3 to 5 seconds at f9 to f11.
