I like this very much and am trying hard to ensure SWMBO does not see it - I can already hear her 'Oh, that's nice, could you....'
I've been looking as best as the photos will let me, I cannot make out the method used for the Chrome rod. Are the Cups hollowed off centre to give a deeper rim at the back, or have you inset something for the rod to rotate around.
I can see shiny bits in the full tower, do I assume that there are magnets inset to hold the piece in-line or are they something I've not thought about?
