Presenting some materials at work this week, I realized I wanted to mark up the screen at select times while I was talking. While a laser pointer would have been sufficient to get people to look at an item of interest at a given time, it would not allow me to further illustrate any points.
Enter the tiny software program called ZoomIt. At your whim, you can freeze a screen, and proceed to draw, type, and otherwise mark it up as if it were a whiteboard. When you are done, it all erases and you are back to your original screen/presentation.
The amusing thing is that this small feature was almost as impressive as the stuff I was talking about. Almost ;)
ZoomIt is available alongside other useful utilities in the Sysinternals collection.
