Maybe, this is one of the strangest screensavers I've downloaded. It is called Amazing Berlin Screensaver, but it features an animated 3D scene of a coastal city, more akin to New York than to Berlin, with a futuristic tower, which seems to be the Fernsehturm (TV tower), located near Berlin's Alexanderplatz. The size of the tower and of the dome located behind it is highly exaggerated and unnatural. Also, the background color can result too lurid for some people. The screensaver has an animated water effect and sounds. The effect looks pretty unnatural too, and the sounds are more suitable for a forest scenery.
The screensaver has some customizable settings that are accessible from its control panel. You can set the DirectX quality of the animation, and turn the sound effects on and off. Also, you can create a custom playlist with your favourite songs to play when the screensaver is active. Apart from the disadvantages early discussed, the installation wizard asks you to install the ScreensaversList toolbar and to change your browser's startup page. Although you can undo these changes in any moment, these are pretty annoying. Use this product at your own risk.
