I have some suggestions to make it better. Like the poster above, I do agree that
1) There should be fish coming closer to the screen instead of staying so far away and bunched up in the middle.
2) Have three layers of fish, one being at the distance, some closer to the front, and others that randomly appear to be in front of the screen.
3) Perhaps have the fish swim or scurry away as the shark gets near them, especially the ones close to the front of the screen. That would be impressive and make it unique compared to sharkvisions and matrox.
4) Have an option to choose even more fish than 100
I have tried atlantis3d sharkvisions demo a few months back and liked the moving camera effect, although I know it would be taxing on most video cards and probably wont find its way into this screensaver.
