Windows and Walls

My new post, as you all remember, will be entirely dedicated to Windows and Walls.
As seen in front of the Window:

• What I like in the Windows most - is that they ideally comply with Walls;
• Speaking about the Walls... You know... Walls is Walls.

And for now, keep silence and watch their inspiring dance:

Window. Wall. Window. Wall. Window. Wall. Window. Wall...

Once again:

Window. Wall. Window. Wall. Window. Wall. Another One. Fall.

Window. Wall.
