I found the following story on C|Net, the computer news network, 
www.news.com/
  The story is copyrighted by Reuters.  
Some enterprising soul may want to check this thing out.  Who 
knows, we may be able to get a better feel for what's going on on 
our screens, and do so at a more affordable price than for other 
systems already under development.
