mark gerwing I don't have any close up shots, but they are pretty simple - 1/2" dia. threaded rod with stainless steel nuts and washers. The shelves themselves are 3/4" maple, clear finished.
For an even more seamless look, take out the cabinet frame and install shelving to replace the cabinetry. To get a similiar look in front of a window, try DIY glass shelving.
Open, see-through shelves. I know the frig will be on part of the wall separting the kitchen and hall, but could some of the wall be done as open, see-though shelves ?
