You're not still using those mundane yellow sticky notes are you? There's a whole world of creative adhesive notational options available to you these days, including these translucent full moons which will actually appear to glow when stuck to your monitor.
It's the perfect way to remember to call your boss, pick up milk, or start a private company offering trips to the moon for $155 million. And since they're made from see-through tracing paper, they can be used to easily annotate documents. Try that with your yellow post-its.
