I find it hard to believe that no one would have tried this before - and in fact from the article "this idea had been 'lifted' from Dale Pond at a 1989 conference in Switzerland and no credit given to Dale".
It had probably been worked on long before 1989 by someone else...
None of the above actually answers the question though of whether this was a truly effective and efficient means of accomplishing this. Whether he invented it or someone else did, I wonder if anyone's actually using this technology?
