To Display JCrystal Images These pages use a Java applette named JCrystal to create a three dimentional image in two dimentions. To see the images, you need to have Java installed on your computer, and have it and Active X enabled. If you do not trust either Java or Active X, you can still view thes pages, but you will miss out on some interesting images of crystals that you can manipulate with your mouse and keyboard. I can understand concerns over security, several years ago I contracted a computer virus from a U.S. Government weapons laboratory web site. The business hosting service I use is Yahoo.com, who have to date been quite successful in preserving the integrity of this site. If you examine the HTML code that I use, it is very straight forward. At the bottom of my code is script added by Yahoo to track the statistics of how many people are visiting each page, and what type of computer and system they have. This added script is a source of cookies used while you are herewhich may be deleted after your visit, or at any time during. To my knowledge, there is no effect on your viewing these pages if cookies are blocked.
