Have had this for 20 days and it runs great

Dont know what everyone is complaining about. This is not supposed to be a screensaver. It is a 3d wallpaper. I have it set up to run on my secondary monitor. I changed my background pic to a Tardis in outer space. I have the fish set to a large number of varied species with the water set to full. It is cool looking. Since i use two 27 inch screens I have extra real estate so its fun to have different backgrounds/3d wallpapers on both. I have a 3.4ghz with 16gb of mem running lion 10.7.2. I have this set to open up with my computer starts up. It runs flawlessly. I have many other products from this creator and they all run great on my system. I have his actual screensavers that I bought from his web site. I think that apple does not allow actual screensavers to be sold so this is a compromise.
Bottom lin folks is this runs just fine. I run multiple applications and I have never noticed any difference in performance. This is just fun. I also run the WhiteNoise app all the time with water running sounds so it all makes a great affect to my work space.
