Stars

I know it's totally random for a building to just have stars on it. I have noticed everyday this week as I have driven to work that buildings like the saratoga and the building right across the street have five point stars on them. It has been way to cold to stand out there to get a picture and as you can tell from my previous post I am having trouble getting them uploaded. I just am curious why these buildings have these stars and if there is a real purpose behind them. I'm going to have to dig into some google time and see what I can figure out. If anything else I think it make the building unique from other ones I have seen in different cities.
