I have seen this around my feeds for a week or so and I have stoped to watch it each time I see it!  It is fascinating.  I first noticed it on Geekwire.

In 2015, a 360 degree camera was placed on the Space Needle.  The purpose, to capture Seattle’s growth over the next 50 years.  Yes, is will be there until 2065!  While I am sure the 50 year view will blow our minds, the three year mark is no less impressive.  Just watch as building literally grow out of the ground.
