Smoothboard 2.0 or another Wii Interactive whiteboard can be used for this. All you would have to is to put an IR LED at the tip of your finger and a button under your thumb, wire these to a resistor and a small battery pack and you are good to go.

Truly tracking a finger has also been done (well tried) with OpenCV, short for open computer vision, and OpenFrameworks library. I have tried a lot of these web-cam mouse systems though and they are really disappointing. The trouble is that all the computer can do is try to look for a patch of color in the video frame, and your fingertip is the same color as the rest of your hand, and the same color as your face. So the tracking spreads out across your entire hand or your face. It really does not work at all yet. MIT also developed a system based on a colorful glove. I have not tried that, but if you see the glove I think that you would agree that an IR pen glove is far easier to make, and far less "nerdy" looking to use. Ok, it's debatable. It depends on whether you want to look like a BORG or a Clown. :-)
