Lines on a building

I seem to have this thing for lines just at present. Thank you so much to all those good folk who have been kind enough to remember me and who dropped in to comment on my last entry. My track record of regular blipping has been pretty iffy in recent times. I can't promise to post on a regular basis but for the first time in ages I find myself "seeing" images again. 

This is the side of a building which houses an "indoor skydiving" facility. You jump off a platform into empty space (doesn't everyone?) and a gigantic fan, below, provides a column of air to hold you up .... riiiiight.   Don't think I'll be trying it anytime soon. Has anybody else tried it? I cannot help but imagine the SPLAT sound which follows almost immediately after the onset of a power failure.
