Because of some recent posts devoted to odd electrical problems, I'd like to see a blog started on how anyone has handle(d) these.  (I'd prefer a MRH article but I'll take examples and helpful information on techniques wherever I can get them.)

For this blog I'd like to see folks describe, in as much detail as they're willing to provide, answers to the following questions:

My layout room is approximately 17' square with 2 large windows on opposite walls I'm trying to figure out how to deal with.  The track plan calls for 2 shelves circling the room's perimeter, which means crossing these windows at two different levels.  I'm wracking my brain trying to think of a way to conceal the windows behind a backdrop (one combined piece or split per level or...?) yet make it possible to occasionally access and open the windows for ventilation (during activities that generate fumes of some kind [airbrushing, hot-wire foam cutting, etc.]).&nb

There have been several posts here and on other forums about the use of LED strips for overall layout lighting.  In general those who try it seem to be having reasonable results, though some have felt it necessary to augment it with more conventional devices in some way, e.g. for spot effects.  With the higher luminosity varieties (5050s), low power consumption, a low amount of waste heat and a low and easily concealed profile, LEDs offer a lot of advantages.
