Pen Attention - Highlights Your Pen Cursor for Presentations
Kenrick, an Associate Professor of Computer Science at the University of Alaska Anchorage, posted a blog entry in which he highlights something he calls "PenAttention." It's a little add-in he created that creates a sort of halo around the pen cursor. Usually, the cursor looks like the tip of a pen. With the add-in, you can also use the cursor as a pointing device. This is super useful when using a Tablet PC for a classroom lecture or a presentation.

Kendrick also got a nod from The Chronicle of Higher Education.
The program is free and requires .NET 2.0 or higher and Windows XP Tablet or Windows Vista with a tablet pen.
