I guess that arch (see last entry) looks pretty okay when used in a room of evenly distributed lighting - and it looks great outdoors.

If I release the arch (IF), you MUST promise me you'll use it in well-lit areas, or darker areas provided the amount of light that shades each piece is about equal. The worst enemy of this expanding arch is the sideways-on window, where the arch piece nearest to the window is the brightest (as in my last entry's piccie). Use lighting or windows opposite the arch though, and all is well.

And it will go nicely with my Never-Ending Privacy Window (below) that I've just queued up for release! Thanks to DavidH, this idea allows you to make your windows as little or as long as you like!
