Note1: If you don't see an animated image, your browser needs the Java plugin.
It's easy and safe to install, and it's free ! Go here to check it out: Java.com
Note2: Unfortunately, Chrome no longer supports the Java (or any other NPAPI) plugin...
So to view this applet, use any other web browser and grant permission if asked.
There are no real security problems here. This is all about web politics!
