chosen: You can turn a pen cap so that it locks into a certain position, so that when the pen is removed from the cap it will write a few words or sentences. You could also thread a piece of yarn through the cap and pen and tie a knot at the end so it stays put - when the pen is removed, the yarn will be pulled tight and write whatever phrase you want. Additionally, you can push the end of a pen into a pencil for an interesting combination, making a multi-nibbed writer. You can also attach a small LED light to the bottom of the pen, making it visible when writing in the dark.
