A strange 3D building from Google earth

As Google just release a new version of Google earth, I tried it on my phone with "I'm feeling Lucky" button ^_^, it lead me to the "Montparnasse Tower", the 3D view is strange on the north-west facing, there is a swirling hole in the upper part of the building.

You could find it by searching "Montparnasse Tower" or go to this link Montparnasse Tower from Chrome.
