Touch-screen capability on regular display

For those who haven't seen it, I wanted to share a video link that showcases some amazing freeware that essentially brings touch-screen functionality to regular displays:http://youtube.com/watch?v=5s5EvhHy7eQAll that's needed to make the magic happen is a Nintendo Wii remote, a bluetooth adapter, an IR light source (either an LED or a piece of reflective tape placed on your fingertip)and the software that developer Johnny Chung Lee has made available on his site:http://www.cs.cmu.edu/~johnny/I did a quick test to see how it worked, and the results are amazing.Although I haven't tried it with FSX, I imagine this software could open up all sorts of new possibilities: touch-screen control of radio stacks immediately comes to mind, but I'm sure there are many others.Charlie
