Amazing soap bubbles slide on top of PC desktop. Bubbles are moving from bottom to top of screen, pulsing and shining with all the rainbow colors. You can choose number of bubbles and its size, speed of bubbles movement and pulsing amplitude. Any picture file (BMP, JPEG and PNG files are supported) on your PC can be selected to use as background image, otherwise current Desktop background will be used (with all icons and opened windows on it).
