Friends, Sorry to follow up my own post but I forgot to mention one thing. Laser pointers are illegal in some jurisdictions. Before you go out in public with a anti-freeze laser pointer, please check with the local authorities to make sure you aren't violating some statute. I don't want someone frozen into a jail cell on my suggestion! Bill PS - My son just sent me a message saying that there are some laser pointer sets that come with 50+ different lenses! -- Bill Innanen <mailto: [log in to unmask]> <http://Bill.Innanen.com> & <http://mni.ms>
