I'm a fair dinkum carpenter on my own behalf. I made my own desks for years, improving them as technology improved and changed. That is a great example of the furniture and cabinetmaker's art. Furniture and cabinet makers are a subset of carpenters just as tool and die makers are a very skilled subset of iron workers and machinists. I, too, wonder about the desk mechanism, and what sort of lighting you use for the indirect, direct and lightbox lighting (especially the lightbox, as they can overheat and need to be really bright). I like halogen as it is nearly natural, not harsh blue as are many CFLs and yet more power-conserving than old fashioned bulbs. I am beginning to play with the new LED applications, and wonder if you have used them?
