The other day, after cleaning my own desk (~4 months of accrued detritus), I thought it would be good to invent a desk filing system where the benchtop can be moved out of the way and a different workspace can be deployed, similar to virtual desktops. A sort of 'physivirtual' desktop. I might just try that at home. My sketchy idea was a vertical cable-driven elevation, followed by a horizontal filing in to ceiling and wall-suspended racks for storing the array of out of use desktops. Electronics in particular is frustratingly object-laden, and any dense workspace array of test equipment tediously immobile. The biggest problem would be vertical space: in a typical room only 3m is available and 2 of that is taken for standing, leading to a maximum benchtop count of 2-3 which is insufficiently attractive to justify the investment.
