Penrose-stairs organiser

Sort desk bits in boxes that step round like the endless staircase

Four long boxes pinwheel round a central well, each one a step taller than the last, like the Penrose stairs in Escher's Ascending and Descending. Clips go in the lowest, pens in the tallest, and the centre takes the phone. It is a useful organiser that looks as though it climbs forever.
