Testing

There is a skyscraper that has recently been finished that I can see from the balcony of my apartment.
There is a big arched structure that sits on top of it and tonight I noticed that it was all lit up with LED lights forming a big screen which they seemed to be testing by displaying a series of patterns.
There was a waving chequered flag, moving clouds against a blue sky, multi-coloured moving dots and this pattern with each segment changing different shades of blue.
I wonder if they will display something else when they have finished testing it.
