Create a screen pointer

I use a pointer made from an old piece of carbon fibre tent pole to point things out on screen whilst instructing clients on how to use their computers. I used to pad the end with a piece of tape, but a blob of Sugru on either end makes it look more professional, visible, easier to hold and doesn't risk scratching the screen. It was also handy when I was on crutches recently to flick switches that were just out of reach from my office chair. (The other end not in shot is identical.)
