CALIBRATING A DIGITAL BILLBOARD
What seems like a bad (or awesome) acid trip is actually a calibration test for a digital billboard. The video (although it appears as an image here) is a test to make sure all of the individual panels are working together to make one complete picture. And actually, if you look about a quarter of the way up from the bottom, you will notice a horizontal line going all the way across and breaking the pattern. This is what they are looking for when doing a test like this.
For everyone else passing by, this calibration test is likely to be much more interesting than the advertisement that will eventually occupy the space!
