I have attempted to make this page as 'surfer friendly' as possible, i.e. you should not need a plug-in to view the animations. BUT there is a big problem with browser compatibility. Animated gif's do have a framerate setting which should be 10 frames per second for my animations, but different browsers and indeed the same browser on different computers displays the animation at different rates, also some ignore the 'loop' message within the gif.
For this reason I have started to include mpeg animations. This means that with a good mpeg player you should be able to set the frame rate to the correct 10 frames per second. Personally I would recommend Vmpeg
