A great, simple idea: forget about the grids of traditional diaries or day planners and have a blank page with an analogue clock outline in the centre, on which you can mark off your appointments. Then the rest of the page is free to do whatever you want with. It acknowledges the fact that the stuff we do tends not to be evenly distributed over the day.

Great ideas for hiding all the wiring and small peripherals on your desk by attaching them - limpet like - to the underside of the desktop.
