AquaticBar is a small but nice application that produces an underwater wave effect while moving the mouse over the Windows taskbar. The taskbar becomes a little bit transparent in order to produce this effect. Taskbar opacity can be modified. Opacity has to be less than 100% in order to produce the effect. This version allows you to set a picture for the background. The only disadvantage is that only BMP format is allowed.
In the trial version only the "Click radius" option of Water settings is enabled, but if you register your copy of AquaticBar you will have access to "Move radius", "Move Intensity", "Ripples strength" and "Restore Defaults" options. You can modify the priority class from Misc Settings but it may cause undesired results including system inestability. You can run AquaticBar at Windows Startup. A tray icon is also installed but you have the option to hide it completely - to open the Settings window you have to run the program again. OS supported: Microsoft Windows 2000, XP, 2003, and Vista.
