In 1992 there was a big lightshow on Canary Wharf Tower, London. I can't remember what it was for now but it ran for a few days and had the letters 'Hi' and some sort of countdown displayed on the windows. You could see it for miles. My Brother in-law was kind enough to take me over there in the evening to do a shoot (Thanks Ian)
Straight shot cleaned up and border added in Photoshop.
