Paper Fish

PaperFish is an application that puts images of fishes on your Mac. I guess you could call this a screensaver, but it is not quite one.

The application puts paper fishes that look like cut-outs on your desktop. There are different types of fishes and you can set how many of them should be on the screen at the same time and how big they are. But, the catch is that they will only be shown on your desktop, and not on the top of other running applications. That is the only reason why you would want to use this as a screensaver. Also, you can\\\'t click any icons on your desktop when a fish is on the top of it. Once in
a while, a fish will flash at the top of running application but that seems like a bug more than a feature. When PaperFish is running, you will see an icon on your dock. If you click the icon and then open the preferences window from the menubar,
you will be able to customize the additional settings. Here, you can set the number of fishes that you see on the screen from 0 to 25. You can also choose between Angel Fish, Blue Tang, Clown Fish, Domino Fish and Emperor Tang and set
their sizes. In short, the fish looks good and the movement is fluid and almost believable. However, I found that having fish swimming around my desktop wasn\'t very useful, and it became the nuisance very soon.
