This software downloaded quickly and completely in just a few seconds. I read the 'read me' file, as I always do, and installed it and activated with no problems at all. I am on my web browser now, which is Firefox, and I can see the wall paper animated, and running in the background. I like it, because it has options for different colours and speeds as well. I am running it on a laptop with a beautiful big 17.5 inch screen, and there are no lags, or any issues that such older problems had in the 'old days'. All in all, I'd give it a 100% thumbs up ! People who enjoy animating their desktops, or use screen savers, will enjoy this freebie. I LOVE it ! Thanks very much !!!
